Vedclass · Answer

(B) According to $Prevost's$ theory of heat exchange,every body at a temperature above $0 \ K$ emits and absorbs thermal radiation simultaneously.When a body is in thermal equilibrium with its surroundings,its temperature remains constant.This implies that the rate of heat energy absorbed by the body must be exactly equal to the rate of heat energy emitted by the body.Therefore,the net heat exchange is zero,and the body maintains a constant temperature equal to that of the surroundings.

$A$ body is in thermal equilibrium with its surroundings. This is because .....
