Why 100 Efficient Engine Is Not Possible?

Why 100 Efficient Engine Is Not Possible? It is impossible for heat engines to achieve 100% thermal efficiency () according to the Second law of thermodynamics. This is impossible because some waste heat is always produced produced in a heat engine, shown in Figure 1 by the term. Why can’t we have 100 efficiency? Explanation:

Does A Heat Engine That Has A Thermal Efficiency Of 100 Percent?
