Two moles of Helium gas (γ = 5/3) are initially at temperature 27 o C and occupy a volume of 20 litres. The gas is first expanded at constant pressure until the volume is doubled. Then it undergoes an adiabatic change until the temperature returns to its initial value.what is the total change in internal energy of the helium?
