Question

Quizplus · Accepted Answer

For an isothermal process, the change in entropy is given by:$$\Delta S = nR \ln \left(\frac{V_2}{V_1}\right)$$where n is the number of moles of gas, R is the ideal gas constant, and V1 and V2 are the initial and final volumes, respectively.

If N Moles of an Ideal Gas Are Compressed Isothermally nCv∫dT/Tn C _ { v } \int d T / TnCv​∫dT/T

If N Moles of an Ideal Gas Are Compressed Isothermally $n C _ { v } \int d T / T$
