The solubility of oxygen ( $O_2$ ) in water at various temperatures is recorded in the table below:

Water Temperature (°C)	Dissolved $O_2$ Solubility (mg/L)
0	14.6
10	11.3
20	9.1
30	7.5
40	6.4

Based on the data table, determine whether the following statement is true or false: A line graph representing these data would feature a line or curve with a negative slope, showing that dissolved oxygen solubility decreases as water temperature increases.

Doğru

Cevabı ve açıklamayı göster

Cevap: True

Cevap

True

The data table displays an inverse relationship between water temperature and dissolved oxygen solubility. When plotted on a coordinate plane with water temperature on the x-axis and dissolved oxygen solubility on the y-axis, the resulting curve trends downward from left to right. This downward trend corresponds to a negative slope, making the statement true.

Adım Adım Çözüm

1

Analyze the relationship between the two variables in the table.

As water temperature increases (

0 \rightarrow 10 \rightarrow 20 \rightarrow 30 \rightarrow 40

°C), the solubility of dissolved oxygen decreases (

14.6 \rightarrow 11.3 \rightarrow 9.1 \rightarrow 7.5 \rightarrow 6.4

mg/L).

Understanding the trend in the numerical data is the first step in translating the table to a graphical format.

2

Determine how this relationship translates to a line graph.

An inverse relationship where the dependent variable (

y

, solubility) decreases as the independent variable (

x

, temperature) increases translates to a line or curve that falls from left to right.

Identifying that a falling line represents a negative slope allows us to evaluate the accuracy of the statement.

Atmospheric scientists measured the mixing ratio of methane ( $\text{CH}_4$ , in $\text{ppm}$ ) and carbon monoxide ( $\text{CO}$ , in $\text{ppb}$ ) at various altitudes above sea level ( $\text{km}$ ) during an atmospheric survey, as shown in the table below:

Altitude ( $\text{km}$ )	Methane ( $\text{CH}_4$ , $\text{ppm}$ )	Carbon Monoxide ( $\text{CO}$ , $\text{ppb}$ )
0	1.85	120
3	1.78	95
6	1.65	70
9	1.48	48
12	1.20	30

Statement: If these tabular data are translated into a line graph plotting atmospheric concentration versus altitude ( $0$ to $12\text{ km}$ ), both gases will be represented by curves with negative slopes, and carbon monoxide will show a larger overall percentage decrease than methane across the altitude range.

Doğru

Yanlış

Cevabı ve açıklamayı göster

Cevap: True

Cevap

The statement is true because both trace gases decrease in concentration as altitude increases, resulting in negative slopes for both plotted curves, and carbon monoxide undergoes a

75.0\%

decrease compared to a

35.1\%

decrease for methane.

The statement accurately translates the tabular data into graphical features. Both gas concentrations decrease steadily with increasing altitude, establishing negative slopes. Additionally, carbon monoxide experiences a

75.0\%

drop versus methane's

35.1\%

drop, confirming that carbon monoxide has the larger overall percentage decrease.

Adım Adım Çözüm

1

Analyze the concentration trend for each gas as altitude increases from

0\text{ km}

to

12\text{ km}

.

Methane decreases from

1.85\text{ ppm}

to

1.20\text{ ppm}

, and carbon monoxide decreases from

120\text{ ppb}

to

30\text{ ppb}

.

Determining whether concentrations increase or decrease establishes the direction of the slope on a concentration versus altitude graph.

2

Determine the slope sign for both curves on a line graph.

Since both concentrations decrease continuously as the horizontal axis (altitude) increases, both curves display negative slopes.

Translating tabular data where the dependent variable decreases while the independent variable increases yields a negative slope.

3

Calculate and compare the percentage decrease for both gases from

0\text{ km}

to

12\text{ km}

.

Methane percentage decrease =

\frac{1.85 - 1.20}{1.85} \times 100\% \approx 35.14\%

. Carbon monoxide percentage decrease =

\frac{120 - 30}{120} \times 100\% = 75.00\%

.

Evaluating relative percentage changes verifies whether carbon monoxide experienced a greater proportional reduction than methane.

Cevabı ve açıklamayı göster

Cevap

The 20°C reaction condition matches the line with a steady, low positive slope reaching 17 mL without plateauing; the 30°C reaction condition matches the curve with a moderate initial slope flattening near 29 mL; and the 40°C reaction condition matches the steep curve reaching a plateau at 40 mL by minute 8.

Each temperature condition in the table exhibits a unique rate of

CO_2

generation over time. The 20°C data shows steady non-zero growth up to 17 mL, the 30°C data demonstrates decelerating growth reaching 29 mL, and the 40°C data displays rapid initial growth that reaches a constant maximum of 40 mL (plateau) at minute 8.

Adım Adım Çözüm

1

Examine the volume trend over time for the 20°C trial in the table.

The volume rises from 0 mL to 17 mL with steady increments of 3–4 mL per 2-minute interval, showing no leveling off.

A constant rate of increase translates directly to a linear trend with a steady positive slope.

2

Examine the volume trend over time for the 30°C trial in the table.

The volume increases from 0 mL to 29 mL, with interval gains decreasing from 9 mL to 2 mL near the end.

Decreasing gains over equal time intervals translate to a curve whose slope flattens gradually over time.

3

Examine the volume trend over time for the 40°C trial in the table.

The volume rises rapidly to 38 mL by minute 6 and remains unchanged at 40 mL at minutes 8 and 10.

An unchanged measurement across consecutive time points translates to a horizontal plateau on a line graph.

Hydrogeologists evaluated the hydraulic conductivity ( $K$ , in $\text{m/day}$ ) of four sediment types under three compaction levels ( $1.4\text{ g/cm}^3$ , $1.6\text{ g/cm}^3$ , and $1.8\text{ g/cm}^3$ ). The results are presented in the following table:

Sediment Type	$K$ at $1.4\text{ g/cm}^3$ (m/day)	$K$ at $1.6\text{ g/cm}^3$ (m/day)	$K$ at $1.8\text{ g/cm}^3$ (m/day)

Statement: If this data were translated into a line graph with compaction density on the horizontal axis and hydraulic conductivity ( $K$ ) on the vertical axis, the lines for all four sediment types would show a positive slope from left to right.

Doğru

Yanlış

Cevabı ve açıklamayı göster

Cevap: False

Cevap

The statement is False because higher compaction density leads to lower hydraulic conductivity for all four sediment types, which translates to a negative slope on a line graph.

The statement is incorrect because the tabular data shows an inverse relationship between compaction density and hydraulic conductivity (

K

). As compaction density increases from left to right along the table headers (

1.4 \rightarrow 1.6 \rightarrow 1.8\text{ g/cm}^3

), the corresponding

K

values decrease for all four sediment types. When translated into a line graph with density on the x-axis and

K

on the y-axis, lines that fall from left to right exhibit a negative slope, not a positive slope.

Adım Adım Çözüm

1

Identify the independent variable for the horizontal axis and the dependent variable for the vertical axis.

Compaction density (

1.4

,

1.6

,

1.8\text{ g/cm}^3

) is on the horizontal (

x

) axis, and hydraulic conductivity (

K

) is on the vertical (

y

Establishing axis assignment is the first step in translating tabular data into graphical form.

2

Examine the trend of hydraulic conductivity (

K

) values as compaction density increases across each row.

For Clay (

0.002 \rightarrow 0.001 \rightarrow 0.0005

), Silt (

0.05 \rightarrow 0.02 \rightarrow 0.008

), Fine Sand (

4.5 \rightarrow 2.1 \rightarrow 0.9

), and Coarse Gravel (

120.0 \rightarrow 85.0 \rightarrow 50.0

),

K

consistently decreases as density increases.

Determining the direction of change in

y

relative to

x

reveals the graphical slope.

3

Translate the observed mathematical trend into a graphical feature (slope direction).

A relationship where

y

decreases as

x

increases forms a downward line from left to right, which defines a negative slope, making the claim of a positive slope false.

Translating inverse data trends to graphs requires correctly associating decreasing values with negative slopes.

Cevap: A line graph plotting Incubation Temperature ( $^\circ\text{C}$ ) on the x-axis and Breakdown Rate ( $\text{mg/L/hr}$ ) on the y-axis, where the curve rises from a point at $(10, 2.0)$ to a peak at $(30, 12.0)$ , before declining to $(50, 1.0)$ .

Cevap

The correct line graph plots Incubation Temperature on the horizontal x-axis and Breakdown Rate on the vertical y-axis, forming a curve that increases to a peak value of 12.0 mg/L/hr at 30°C and then drops to 1.0 mg/L/hr at 50°C.

The correct graph properly places Incubation Temperature on the x-axis and Breakdown Rate on the y-axis. The data points from the table demonstrate an initial rise in rate up to 30°C (12.0 mg/L/hr), followed by a decline as temperature increases further to 50°C (1.0 mg/L/hr), which corresponds exactly to a peaked curve.

Adım Adım Çözüm

1

Identify axis assignments for translating tabular data to a line graph.

The independent variable (Incubation Temperature in °C) belongs on the horizontal x-axis, and the dependent variable (Breakdown Rate in mg/L/hr) belongs on the vertical y-axis.

Standard ACT scientific graphical conventions place controlled/independent variables on the x-axis and measured/dependent variables on the y-axis.

2

Trace the key data coordinates from the table

(x, y)

.

Points are

(10, 2.0)

,

(20, 5.5)

,

(30, 12.0)

,

(40, 8.5)

, and

(50, 1.0)

.

Accurate format translation requires verifying specific numeric values at each data level.

3

Analyze the trend of the data points.

The rate increases from 10°C to 30°C (reaching a peak of 12.0 mg/L/hr), then decreases from 30°C to 50°C.

The curve must visually reflect this unimodal (bell-shaped) trend.

Compound Y	$0.8$	$0.8$	$0.8$
Compound Z	$2.0$	$4.0$	$6.0$

Cevap

Compound W matches the concave-up exponential curve; Compound X matches the negative slope of

-0.03\text{ mmol/L}\cdot\text{s}\cdot\text{K}^{-1}

; Compound Y matches the horizontal zero-slope line at

0.8\text{ mmol/L}\cdot\text{s}

; Compound Z matches the positive slope of

0.04\text{ mmol/L}\cdot\text{s}\cdot\text{K}^{-1}

.

Each tabular dataset directly translates to a specific graphical shape or slope: exponential doubling yields a concave-up curve; equal decreases yield a linear negative slope of

-0.03

; constant values yield a zero-slope horizontal line; equal increases yield a linear positive slope of

0.04

.

Analyze Compound W's data trend

The rates are

1.2

,

2.4

, and

4.8

at

300\text{ K}

,

350\text{ K}

, and

400\text{ K}

Dividing consecutive rates yields

\frac{2.4}{1.2} = 2

and

\frac{4.8}{2.4} = 2

, showing exponential growth (concave-up curve with a doubling pattern).

2

Analyze Compound X's data trend and calculate slope

Rate decreases from

5.0

to

3.5

to

2.0

as temperature rises from

300\text{ K}

to

400\text{ K}

.

The rate change per kelvin is

\frac{2.0 - 5.0}{400 - 300} = \frac{-3.0}{100} = -0.03\text{ mmol/L}\cdot\text{s}\cdot\text{K}^{-1}

.

3

Analyze Compound Y's data trend

The rate remains unchanged at

0.8\text{ mmol/L}\cdot\text{s}

across all temperatures.

A constant value across the independent variable axis translates to a horizontal line with zero slope.

4

Analyze Compound Z's data trend and calculate slope

Rate increases linearly from

2.0

to

4.0

to

6.0

.

The slope is

\frac{6.0 - 2.0}{400 - 300} = \frac{4.0}{100} = 0.04\text{ mmol/L}\cdot\text{s}\cdot\text{K}^{-1}

Oceanographers measured the sound velocity in seawater at various depths under two different salinity levels ( $34\text{ ppt}$ and $36\text{ ppt}$ ). The results are recorded in Table 1 below:

Depth (m)	Sound Velocity at 34 ppt (m/s)	Sound Velocity at 36 ppt (m/s)
0	1,520	1,523
200	1,495	1,498
600	1,475	1,478
1,000	1,470	1,473
1,500	1,480	1,483
2,000	1,490	1,493

Statement: If the data in Table 1 were translated into a two-line graph plotting Sound Velocity (m/s) on the y-axis against Depth (m) on the x-axis, both curves would reach a minimum value at a depth of $1,000\text{ m}$ , and the curve representing $36\text{ ppt}$ salinity would be positioned strictly above the curve representing $34\text{ ppt}$ salinity across all measured depths.

Cevap: True

Cevap

The statement is True.

The statement accurately reflects the conversion of the tabular data into a line graph. In Table 1, both sound velocity columns drop to their lowest values (

1,470\text{ m/s}

and

1,473\text{ m/s}

) at a depth of

1,000\text{ m}

before rising again, creating a V-shaped curve minimum at

x = 1,000\text{ m}

. Additionally, at every listed depth, the value for

36\text{ ppt}

is higher than for

34\text{ ppt}

, placing the

36\text{ ppt}

curve vertically above the

34\text{ ppt}

curve.

Adım Adım Çözüm

1

Analyze the trend along the vertical axis variable (Sound Velocity) as a function of the horizontal axis variable (Depth) for both datasets.

For

34\text{ ppt}

, velocities are

1,520 \rightarrow 1,495 \rightarrow 1,475 \rightarrow 1,470 \rightarrow 1,480 \rightarrow 1,490

. The lowest point (minimum) occurs at

1,000\text{ m}

(

1,470\text{ m/s}

). For

36\text{ ppt}

, velocities are

1,523 \rightarrow 1,498 \rightarrow 1,478 \rightarrow 1,473 \rightarrow 1,483 \rightarrow 1,493

. The lowest point also occurs at

1,000\text{ m}

(

1,473\text{ m/s}

).

Determining where the graph reaches its lowest point requires identifying the minimum y-value for each x-value series.

2

Compare the relative vertical height (y-values) of the two salinity series across all depth levels (x-values).

At depth

0\text{ m}

:

1,523 > 1,520

; at

200\text{ m}

:

1,498 > 1,495

; at

600\text{ m}

:

1,478 > 1,475

; at

1,000\text{ m}

:

1,473 > 1,470

; at

1,500\text{ m}

:

1,483 > 1,480

; at

2,000\text{ m}

:

1,493 > 1,490

.

A curve with higher y-values at every x-value will be graphed higher up (above) another curve.

3

Synthesize the graphical behavior described in the statement with the tabular evidence.

Both curves reach a minimum at

1,000\text{ m}

and the

36\text{ ppt}

line remains strictly higher on the y-axis than the

34\text{ ppt}

line at all points. Thus, the statement is true.

The textual description of the proposed graph matches the tabular data perfectly in both shape (minimum location) and relative alignment.
