Question

Based on the first law of thermodynamics, which one of the following is correct?, For an isochoric process, ΔE = − q, For an adiabatic process, ΔE = − w, For an isothermal process, q = W, For a cyclic process, q = − W

MARKS App · Accepted Answer

(a) For isochoric process, ΔV = 0 W = pΔV = 0 ∴ ΔE = q (b) For adiabatic process, q = 0 ΔE = W (c) For isothermal process, ΔT = 0 and ΔE = 0 q = − W (d) For cyclic process, state functions like ΔE = 0 q = − W
