When 18.9 kj is transferred to a gas sample in a constant volume adiabatic container with a calorimeter constant of 2.22 ki/k, the temperature of the gas (and the calorimeter) increases by 8.06 k
(a) what is the heat capacity of the sample?
(b) if the sample has a mass of 0.5 kilograms, what is the specific heat capacity of the substance?
(c) if the sample is krypton, what is the molar heat capacity at constant volume of krypton? the molar mass of krypton is 83.8 grams/mole.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
