A vertical cylinder contains N atoms of an ideal gas and is closed off by a piston having mass m and area a. The acceleration due to gravity is g. The gas has a heat capacity Cy which is independent of temperature. (Note that the preceding sentence contains the words "heat capacity" and does not contain the words "specific heat.") Neglect the heat capacity of the cylinder and piston, ignore friction, and the entire system is thermally insulated. The piston...
