Zorluk: KolayIdentifying Points of Agreement

Two scientists discuss the behavior of a newly discovered gas at high pressures.

Scientist 1
At high pressures, the gas molecules attract each other, causing the measured volume to be smaller than the volume predicted by the ideal gas law. These attractive forces only become significant at pressures above 10 atm10\text{ atm}.

Scientist 2
At high pressures, the gas molecules repel each other, causing the measured volume to be larger than the volume predicted by the ideal gas law. These repulsive forces only become significant at pressures above 10 atm10\text{ atm}.

Based on the descriptions, both Scientist 1 and Scientist 2 agree with which of the following statements regarding the gas?

  1. The forces between the gas molecules become significant only at pressures greater than 10 atm10\text{ atm}.Cevap
  2. B
    The molecules of the gas attract each other when the pressure is high.
  3. C
    The measured volume of the gas is larger than the volume predicted by the ideal gas law at high pressures.
  4. D
    The gas behaves in accordance with the ideal gas law at all pressures.

Cevap

The forces between the gas molecules become significant only at pressures greater than 10 atm10\text{ atm}.
The correct answer identifies the pressure threshold (10 atm10\text{ atm}) above which molecular interactions become significant. Both Scientist 1 (for attraction) and Scientist 2 (for repulsion) agree that these forces only impact the gas behavior significantly at pressures above this value.

Adım Adım Çözüm

1
Identify the claim made by Scientist 1 regarding the pressure threshold of the molecular interactions.
Scientist 1 states that attractive forces become significant only at pressures above 10 atm10\text{ atm}.
To find a point of agreement, we must determine what threshold or condition each scientist establishes for non-ideal behavior.
2
Identify the claim made by Scientist 2 regarding the pressure threshold of the molecular interactions.
Scientist 2 states that repulsive forces become significant only at pressures above 10 atm10\text{ atm}.
This allows comparison with the threshold established by Scientist 1.
3
Compare the two thresholds to find the shared assertion.
Both scientists agree that the molecular forces (regardless of whether they are attractive or repulsive) become significant only at pressures above 10 atm10\text{ atm}.
The correct option must represent a shared premise or conclusion between both viewpoints.
