2. A gas confined in a cylinder, initially at 20C,100kPa and with a specific volume of 0.0244m3/mol, is undergoing the following series of processes: Step 1: A constant pressure process when it receives 150J of work Step 2: A constant volume process when it receives 1500J of heat Calculate, on the basis of 1 mole of gas, the total change of internal energy and enthalpy as well as the total work and heat transferred. For all processes, assume that PV/T remains constant and that CVV=20.785 and CP=29.100Jmol1K1
