A vertical cylinder with a heavy piston contains air at 305 K. The initial pressure is 2.80 x 10° Pa, and the initial volume is 0.440 m. Take the molar mass of air as 28.9 g/mol and assume C (a) Find the specific heat of air at constant volume in units of J/kg - °C. 719 v J/kg · °C. (b) Calculate the mass of the air in the cylinder. kg (c) Suppose the piston is held fixed. Find the energy input required to raise the temperature of the air to 785 K. kJ
