Question

1.65 moles of an ideal gas, for which Cv, m = 3R/2, is subjected to two successive changes in state; (1) From 39.0 degree C and 100. times 103 Pa, the gas is expanded isothermally against a constant pressure of 16.5 times 103 Pa to twice the initial volume. (2) At the end of the previous process, the gas is cooled at constant volume from 39.0 degree C to -25.0 degree C. Calculate q, w, Delta U, and Delta H for each of the stages. Also calculate q, w, Delta U, and Delta H for the complete process.
