3. Two moles of helium (y=5/3) are initially at a temperature of 27 °C and occupy a volume of 20L. The helium is first expanded at constant pressure until the volume has tripled, and then adiabatically until the temperature returns to its initial state. given for helium Cp = 20.78 J/mol-k (a) Draw diagram of process in P-V plane (b) What is the total heat supplied in the process (c) What is the total change in internal energy of helium. (d) What is the total work done by the helium. (e) What is the final volume and pressure.
