A body and its surroundings are both at 100°C. The body emits thermal radiation and also absorbs radiation from the surroundings. What is the net thermal energy transfer?
A
Out of the body only, because anything at 100°C emits energy.
B
Zero, because emission and absorption balance at equal temperature.
C
Into the body only, because surroundings contain more matter.
D
Undefined, because radiation is not related to temperature.
