Which of the following statement(s) is/are true? — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

The integral of any exact differential around a closed cycle is zero ($\oint dF = 0$ for state functions like $U, H, G, S$). A process returning to the initial temperature is not necessarily isothermal throughout. An isolated system strictly prevents volume/work changes, not just heat/matter.
