2. 7-23 A rigid tank contains an ideal gas that is being stirred by a paddle wheel. The temperature of the gas remains constant as a result of heat transfer out. The entropy change of the gas is to be determined. Assumptions The gas in the tank is given to be an ideal gas. Analysis The temperature and the specific volume of the gas remain constant during this process. Therefore, the initial and the final states of the gas are the same. Then s, = s, since entropy is a property. Therefore, IDEAL GAS 40 C Heat 200 30 C AS -0 2. 7-23 A rigid tank contains an ideal gas that is being stirred by a paddle wheel.
