A sample of argon of mass 10.4 g occupies 2100 ml at 30 degrees.

(i) Calculate the work done by the gas when is expands isothermally against a constant external pressure of 34.7 k Pa until its volume has increased by 387.2 ml

(ii) Calculate the work done by the gas if the same expansion occurs reversibly.

(iii) What is the change in internal energy for the expansion process in (i) ?

(iv) For the reversible expansion process, what are the values of deltaU, deltaH and deltaS.
