Question

entropy of an isolated system in an isothermal irreversible cycle always........​

Answer 1

An increase in entropy is observed in an isothermal and irreversible cycle of an isolated system

• We know, that the second law of thermodynamics states that the entropy of an isolated system can never decrease or become lower than a given value at a particular time in the universe.
• In an irreversible cycle of an isolated system, the entropy always increases and cannot decrease.
• Isothermal process refers to a process that takes place at a constant temperature, that is, ΔT=0.

Thus, the entropy of an isolated system in an isothermal irreversible cycle always increases.
