Chemistry Question on Thermodynamics
The freezer in a refrigerator is located at the top section so that
A
the entire chamber of the refrigerator is cooled quickly due to convection
B
the motor is not heated
C
the heat gained from the environment is high
D
the heat gained from the environment is low
Answer
the entire chamber of the refrigerator is cooled quickly due to convection
Explanation
Solution
As hot air has lesser density than the colder air and rises above, the freezer is kept at the top section, so that hot air from downward section can rise to the freezer and gets colder. This is an example of convection process.
