Work done on a system when one mole of an an ideal gas at 500 K is compressed isothermally and reversibly to 1/10th of its original volume. (R = 2cal)

The work done on the system when one mole of an ideal gas is compressed isothermally to a final volume of 0.01 m^(3) at constant external pressure of 5 bar is 20 kJ. What is initial volume of the gas?

Calculate the work done (in joules) when 0.2 mole of an ideal gas at 300 K expands isothermally and reversible from an initial volume of 2.5 litres to the final volume of 25 litres.

Calculate the work done (in joules) when 0.2 mole of an ideal gas at 300 K expands isothermally and reversible from an initial volume of 2.5 litres to the final volume of 25 litres.

Thermodynamics deals with energy changes of macroscopic systems. 3 moles of an ideal gas at 1.5 atm and 25^@C expands isothermally in a reversible manner to twice its original volume agaisnt an external pressure of 1 atm. Calculate the work done. [R 8.314 J//K//mol
