Four moles of an ideal gas at 2.5 atm and 27^(@)C are compressed isothermally to half of its volume by an external pressure of 3 atm. Calculate w, q and DeltaU .

Two moles of an ideal gas at 2 atm and 25^@C are compressed isothermally to one third of its volume by an external pressure of 6 atm. Calculate q, w and DeltaU .

Two moles of an ideal gas at 2 atm and 27^(@)C is compressed isothermally to half of its volume by external pressure of 4 atm. The work doen is

A cylinder fitted with a piston contains an ideal gas with a volume of 21 L. the gas is compressed isothermally to 1/3 rd of its initial volume under a constant external pressure of 3 atm. Calculate q, w and DeltaU .

2.5 mole of on ideal gas at 2 atm and 27^@C expands isothermally to 2.5 times of its original volume agains the external pressure of 1 atm.Calculate work done (Given R=0.082 L atm K^-2 mol^-1)

10 litre of an ideal gas at 25 atm and 27^(@)C is expanded isothermally to 1 atm against a constant external pressure of 760 torr. Calualate work done by the gas in litre-atm:

70 gms of nitrogen gas was at 50 atm and 25^(@) C. (a) It was allowed to expand isothermally against a constant external pressure of one atmopshere. Calculate Deltau.Deltaq and Deltaw assuming that gas behaves ideally. (b) Also find out the maximum work that would be obtained if the gas expanded reversibly and isothermally to one atmosphere.

An 'ideal gas enclosed in a cylinder fitted with a piston of volume ZiL is compressed isothermally to 1//3rd of its initial volume, under the influence of 3 atm constant external pressure. Calculate q. w and Delta U.
