One mole of an ideal gas is initially in a chamber of volume 1.0 × 10 − 2 m 3 and at a temperature of 27 ℃. (a) How much heat is absorbed by the gas when it slowly expands isothermally to twice its initial volume? (b) Suppose the gas is slowly transformed to the same final state by first decreasing the pressure at constant volume and then expanding it isobarically. What is the heat transferred for this case? (c) Calculate the heat transferred when the gas is transformed quasi-statically to the same final state by expanding it isobarically, then decreasing its pressure at constant volume.

A cylinder contains 0.100 mol of an ideal monatomic gas. Initially ,the gas is at a pressure of 1.00 x 10^5 Pa and occupies a volume of 2.50 x 10^ -3 cubic meter. If the gas is allowed to expand to twice the initial volume, what is the final temperature if the expansion is adiabatic?
When 20.9 J was added as heat to a particular ideal gas, the volume of the gas changed from 50.0 cm3 to 100 cm3 while the pressure remained at 1.00 atm. (a) By how much did the internal energy of the gas change? If the quantity of gas present was 2.00 *10-3 mol, find (b) Cp and (c) CV.
Consider a well-insulated horizontal rigid cylinder that is divided into two compartments by a piston that is free to move, but does not allow either gas to leak into the other side. Initially, one side of the piston contains 1 m3 of N2 gas at 500 kPa and 120°C while the other side contains 1 m3 of He gas at 500 kPa and 40°C. Now thermal equilibrium is established in the cylinder as a result of heat transfer through the piston. Using constant specific heats at room temperature, determine the final equilibrium temperature in the cylinder. What would your answer be if the piston were not free to move?
