Vedclass · Answer

(D) According to the laws of thermodynamics,energy transformation is never $100\%$ efficient.During any energy conversion process,a portion of the energy is always dissipated as heat,which is often unavailable for further useful work.Therefore,Assertion $A$ is true because heat energy is indeed present/available in the system as a byproduct.Reason $R$ is also true because energy loss (as heat) occurs during every transformation.Since the availability of heat energy in a system is a direct consequence of the energy lost during transformations,$R$ is the correct explanation for $A$.

Assertion $A$: Heat energy is available for the functioning of a system.
Reason $R$: Some amount of energy is lost during energy transformation.
Which option is correct for Assertion $A$ and Reason $R$?
