Question 16

A ceramic test piece transfers energy to and from its surroundings only by radiation. In each second, the test piece absorbs 36 J of energy and emits 36 J of energy. The temperature of the test piece

[1]
A

keeps changing because absorption and emission occur at the same time.

B

increases because the absorbed radiation raises its thermal energy.

C

decreases because the emitted radiation reduces its thermal energy.

D

remains constant because there is no overall change in its thermal energy.
