Two moles of carbon monoxide (CO) start at a pressure of 1.5 atm and a volume of 29 liters . The gas is then compressed adiabatically to 13 this volume. Assume that the gas may be treated as ideal.

(a) What is the change in the internal energy of the gas? Does the internal energy increase or decrease?
(b) Does the temperature of the gas increase or decrease during this process? Explain.

Water at room temperature of 20.0°c is poured into an aluminum cylinder which has graduation markings etched on the inside. the reading in the graduations is 300.0 cc. the cylinder with the water in it is then immersed in a constant temperature bath at a temperature of 100°c. what is the reading for the level of water on the graduations of the cylinder after the water and the cylinder reach thermal equilibrium with the bath? the volume coefficient of expansion of water is 2.07 x 10^-4 k-1, and the linear coefficient of expansion of aluminum is 23.0 x 10^-6 k-1. a) 305.0 cc b) 304.0 cc c) 303.5 cc d) 303.3 cc e) 304.5 cc
