Explain the heat capacity of the gas, at constant pressure

Reference no: EM13490467

0.4 mol of a gas is heated at constant pressure, so that its temperature increases from 21deg C to 79.83 deg C. As a result, the gas expands from 10L to 12L against an external pressure of 0.965atm. The heat capacity of the gas, at constant pressure, is 20.8 J/molK. What is the total energy change delta U (in J) for the gas?
