Question 43

Two heated incubation chambers, P and Q, are identical except that P has an access door on its top surface, and Q has an access door on its bottom surface. Both chambers are initially kept at a temperature well above the room temperature. Both doors are opened for the same short duration of time. Which chamber loses the least amount of thermal energy during this time, and what is the reason?

A

Chamber losing the least thermal energy: P; Reason: warm air rises

B

Chamber losing the least thermal energy: P; Reason: cold air rises

C

Chamber losing the least thermal energy: Q; Reason: warm air rises

D

Chamber losing the least thermal energy: Q; Reason: cold air rises
