Determine the Heat Effects and Work effects

Consider an ideal gas undergoing a series of three thermodynamical operations.
 Operation – 1: The gas is heated at constant volume from 301 K and 1.1 bar to a pressure of 2.1 bar.
 Operation – 2: The gas is expanded in a reversible adiabatic process to a pressure of 1.1 bar.
 Operation – 3: The gas is cooled at constant pressure of 1.1 bar to 301 K.

Determine the (a) Heat Effects and (b) Work effects for each step. Assume Cp = 29.3 kJ/kmol K.
