2. A vertical Cylinder with a heavy piston contains air at 300 K. The initial pressure is 3.35*10^5 Pa, and the initial volume is 0.300 m^3. Take the molar mass air as 28.9 g/mol and assume Cv = 5R/2, R = 8.314 J/mol K
a) Find the specific heat of air at constant volume in units of J/kg C
b) Calculate the mass of the air in the cylinder
c)Suppose the piston is held fixed. Find the energy input required to raise the temperature of the air to 691K.
