If n moles of an ideal gas are compressed isothermally from an initial volume V₁ to a final volume V₂, the change in entropy is A) nR ln (V₂/V₁) B) nRT ln (V₂/V₁) C) nk_B ln (V₂/V₁) E) n C_v/T

Question

Quizplus · Accepted Answer

For an isothermal process, the change in entropy is given by: ΔS = nR ln(V2/V1) where n is the number of moles, R is the gas constant, V1 is the initial volume, and V2 is the final volume. Substituting the given values, we get: ΔS = nR ln(V₂/V₁) which is the same as option A.
