Question:

Two moles of an ideal gas occupy a volume V. The gas expands isothermally and reversibly to a volume 3V.
(a) Is the velocity changed by the isothermal expansion? Explain.
(b) Use Eq. (20.23) to calculate the change in entropy of the gas.
(c) Use Eq. (20.18) to calculate the change in entropy of the gas. Compare this result to that obtained in part (b)
Distribution
The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
