In a completely cyclic process starting and ending at identical states, which of the following cycli — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

In a cyclic process, all state functions ($U$, $H$, $S$, $G$) return to their original values, so their cyclic integrals are exactly zero. However, work ($w$) and heat ($q$) are path functions, and their net exchange around a cycle equals the area enclosed in the P-V diagram.
