Helium gas at 119.0 kPa and 329.0 K is located within a cylinder with a piston. Initially the gas occupies 0.4800 m3. While a constant force, F, is applied to the end of the piston so that the pressure inside the cylinder is held constant at 119.0 kPa, 7380.0 J of heat is transferred to the helium gas. The specific enthalpy of helium gas is given by the approximate relation: H(kJ/mol)=.0208*T(Kelvin)
1) What is the final temperature of the helium gas?
2) What is the final volume of the helium gas?
3) What is the work done by the gas?
4) What is the change of the internal energy of the system?
