Chemistry - Thermodynamics - I Question with Solution | TestHub

E is a state function, so it returns to its initial value in a cycle. For an ideal gas E depends only on T, so it is zero when T is constant. A real gas has intermolecular forces, so E changes with volume at constant T. A phase change at constant T absorbs latent heat, so Δ E ≠ 0. Ans: (a), (b).
