One gram mole of an ideal gas at `N.T.P` is first expanded isothermally to twice the origional volume. It is then compressed at constant volume, till its pressure is raised to the original value. Calculate the total amount of work done. Given `R= 8.3 mol e^(_1)K^(-1)`.

Three moles of an ideal gas are expanded isothermally and reversibly at 27^(@)C to twice its original volume. Calculate q, w, and DeltaU .

Three moles of an ideal gas at a pressure P_(A) and temperature T_(A) is isothermally expanded to twice its initial volume. It is then compressed at constant pressure to its original , volume. Finally the gas is compressed at constant volume to its original pressure P_(A) (a) Sketch the P-V and P-T diagrams for the complete process. (b) Calculate the net work done by the gas, and net heat supplied to the gas during the complete process.

A mass of ideal gas at pressure P is expanded isothermally to four times the original volume and then slowly compressed adiabatically to its original volume. Assuming gamma to be 1.5, the new pressure of the gas is
