Question 1

An object remains at a constant temperature. Which statement about the thermal energy transfers of the object is correct?

A

There is absolutely no thermal energy transferred to or from the object.

B

The rate at which the object absorbs thermal energy is equal to the rate at which it emits thermal energy.

C

The rate at which the object absorbs thermal energy is greater than the rate at which it emits thermal energy.

D

The rate at which the object absorbs thermal energy is less than the rate at which it emits thermal energy.
