a) An ideal gas occupying a volume of 10.8L at a pressure of 1bar and a temperature of 300 K, is compressed reversibly and adiabatically to a volume of 6.45L. What is its final pressure and temperature? (Note: for thisideal gas, you may assume thatR/Cv= 0.4, or γ=5/3; these represent the same thing.) (b) The heat capacity ratio, γ= 1.20, for a certain ideal gas. By what factor does the pressure changeif the volume is doubled in a reversible adiabatic expansion?
