Vedclass · Answer

(A) The second law of thermodynamics,specifically the Kelvin-Planck statement,asserts that it is impossible for any device that operates on a thermodynamic cycle to receive heat from a single thermal reservoir and produce a net amount of work. This implies that a heat engine must reject some amount of heat to a cold reservoir (sink) to complete the cycle. Consequently,no heat engine can have an efficiency of $100\%$,as some energy must always be dissipated as waste heat. Therefore,the second law of thermodynamics imposes the limitation that a heat engine cannot convert all the heat supplied to it into work.
