0.20 moles of Helium gas that initially occupies a volume of 4.0L under a total pressure of 1.0x10^5 Pa, subsequently undergoes an isobaric expansion to 5.0L followed by an isothermal expansion to 8.0L.

a.) What is the specific heat at constant volume?

b.) What is the specific heat at constant temperature?

c.) What is the initial temperature of the gas?

d.) What are the pressure and temperature of the gas at the end of the isobaric expansion?

e.) What are the pressure, and temperature of the gas after the isothermal expansion?

f.) What is the total work done for the entire process?

g.) What is the internal-energy change of the gas for the entire process? Does the internal energy of the gas increase or decrease? Explain briefly.

h.) What is the total heat transferred for the entire process? Does the gas absorb heat from the surroundings or does it release heat to the surroundings? Explain briefly.

i.) Draw the entire process on the P-V diagram provided below. Label the region on the graph that represents the total work done.
