Difficulty: EasyUnit Conversions

During a science experiment, a liquid is cooled at a constant rate of 0.50.5 degrees Celsius per minute. What is the cooling rate of the liquid, in degrees Celsius per hour?

Answer: 30 degrees Celsius per hour

Answer

The cooling rate of the liquid is 3030 degrees Celsius per hour.
To find the cooling rate in degrees Celsius per hour, we multiply the rate per minute by the conversion factor. There are 6060 minutes in 11 hour. Multiplying 0.50.5 degrees Celsius per minute by 6060 minutes per hour yields 3030 degrees Celsius per hour.

Step-by-Step Solution

1
Identify the initial cooling rate per minute.
0.50.5 degrees Celsius per minute
This is the rate given in the problem statement.
2
Convert minutes to hours by multiplying the rate by 6060.
3030 degrees Celsius per hour
An hour contains 6060 minutes, so the total temperature decrease in one hour will be 6060 times the decrease in one minute.
