A sample of argon of mass 10.4 g occupies 2100 ml at 30 oC .
(i) Calculate the work done by the gas when it expands isothermally against a constant external pressure of 31.1kPa until its volume has increased by 483.1ml.
(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)?
Change is internal energy is zero.
(iv) For the reversible expansion process, what are the values of ΔU, ΔH and ΔS ?
