Please explain thoroughly

Two dm of N2 at 0°C and 500 kPa pressure are expanded isothermally against a constant pressure of 100 kPa until the pressure of the gas is also 100 kPa. Assuming the gas to be ideal, calculate w, q, AU and AH for this process. [-800 J; + 88J; 0; 0]] Three moles of an ideal gas at 100 kPa pressure and 20°C are heated at constant pressure until the final temperature is 80°C. For the gas, C, = 35.56 + 1.34 x 102 T J mol" K'. Calculate the change in the enthalpy of the gas. [7.18 kJ]
