Vedclass · Answer

(B) According to Prevost's theory of heat exchange,every body at a temperature above $0 \ K$ radiates thermal energy to its surroundings and simultaneously absorbs thermal energy from its surroundings.When the temperature of the body $(T_b)$ is equal to the temperature of the surroundings $(T_s)$,the rate of emission of heat energy is exactly equal to the rate of absorption of heat energy.Therefore,the net exchange of heat is zero,and the body remains in thermal equilibrium with its surroundings.Thus,the correct statement is that it radiates the same quantity of heat as it absorbs.
