One kilogram of helium in an insulated piston/cylinder at 47°C and 1000 kPa is expanded in a reversible process to 500 kPa, as shown in the above figure. Find a) the final temperature of helium gas and b) the final volume of helium gas. Helium is an ideal gas with constant specific heats. (for helium R-2.0769 kJ/kg-K, cp-5.1926 kJ/kg-K, c.-3.1156 kJ/kg-K).
