Every heat engine takes heat from a hot body (source), converts a part of it into work and rejects the remaining part to a cold body (sink). A heat engine carries some working substance through a cyclic process during which... * Reversible and Irreversible Process * Cyclic Process * Quasi-Static Process * Heat Energy and Second Law of Thermodynamics * Efficiency of Heat Engine * Refrigerator and Second Law * Equivalence of Clausius and Kelvin Statement * Carnot Engine * Carnot Cycle * Efficiency of Carnot Engine * Thermodynamics Temperature Scale * Absolute Zero and -ve Temperature * Entropy in Reversible Process * Entropy Function * Entropy in Irreversible Process * Free Expansion * Irreversible Heat Transfer * Entropy and Second Law === View online & Download: ===
