    Two moles of a gas ( gamma = 5/3) are initially at temperature 27^@C and occupy a volume of 20 litres. The gas is first expanded at constant pressure returns to its initial value. a) Sketch the process on a P-V diagram b) What are final volume and pressure of the gas? c) What is the work done by the gas?

    0.2m^(3) of an ideal gas at a pressure of 2 MPa and 600 K is expanded isothermally to 5 times the initial volume. It is then cooled to 300 K at constant volume and then compressed back polytropically to its initial state. Determine the net work done and heat transfer during the cycle.

    Three moles of an ideal gas at 300 K are isothermally expanded to five times its volume and heated at this constant volume so that the pressure is raised to its initial value before expansion. In the whole process 83.14 KJ heat is required. Calculate the ratio C_p//C_v of the gas. log. 5 = 1.61 and R = 8.3 Joules/mole K.
