Question

A quantity of a certain perfect gas is compressed from an initial state of 0.085 m3 , 1 bar to a final state of 0.034 m3 , 3.9 bar. The specific heat at constant volume is 0.724 kJ/kg K, and the specific heat at constant pressure is 1.020 kJ/kg K. The observed temperature is 146 K. Determine the specific gas constant, R, The mass of the gas present, and the increase of internal energy of the gas.

A quantity of a certain perfect gas is compressed from an initial state of 0.085 m², 1 bar to a final
state of 0.034 m, 3.9 bar. The specific heat at constant volume is 0.724 kJ/kg K, and the specific
heat at constant pressure is 1.020 kJ/kg K. The observed temperature is 146 K. Determine the
specific gas constant, R, The mass of the gas present, and the increase of internal energy of the
gas.
