Ten grams (10.0 g) of aluminum foil at 30 °C and 0.50 moles of gas at 15 °C are placed in a container whose volume changes to maintain the pressure at 200 kPa. The foil and air come to equilibrium with negligible heat exchange with the container. The specific heat of the gas is cP = 3.5R, where R is the universal gas constant.
(a) Find the final temperature of the foil and gas.
(b) Find the values of Q and ?U for the foil. (Its volume change is negligible.)
(c) Find the work done by the gas.
(d) What are the values of Q and ?U for the gas?
