0.0500 mol of gas occupies a cylinder which is sealed on top by a moveable piston. The piston is circular, with a mass of 30.0 kg and diameter of 5.00 cm. It is supported only by the pressure of the gas in the cylinder. Outside of the cylinder, there is air at 1.00 atm. Initially, the piston is 30.0 cm above the bottom of the cylinder. Heat is then added, causing the gas to expand until the piston is 40.0 cm above the bottom of the cylinder. For this process, find the change in internal energy, the work done by the gas, and the heat which flows into the gas.
a. assuming that the gas is N2.
b. assuming that the gas is neon
