Part A

Quantity A of an ideal gas is at absolutetemperature T, and a second quantity B of the samegas is at absolute temperature 2T. Heat is added toeach gas, and both gases are allowed to expand isothermally.

If both gases were initially atthe same absolute temperature, would they still undergo the sameentropy change?

	No, gas A would undergo the greater entropy change.
	No, gas B would undergo the greater entropy change.
	Yes, both gases would have the same entropy.

Part B

What is the change in entropy of 280 gof steam at100 ?C when it is condensed to water at 100 ?C?

Express your answer to two significant figures and include theappropriate units.
