Two moles of an ideal gas occupy a volume V. The gas expands isothermally and reversibly to a volume 6 V.

A)Is the velocity distribution changed by the isothermal expansion?

B)Explain why ?

C)Use the equation ΔS=klnw2/w1 to calculate the change in entropy of the gas.

D)Use the equation ΔS=Q/T to calculate the change in entropy of the gas.

Compare the result in part (d) to that obtained in part (c).
