11 A gas with a mass of 3 kg has a volume of 3.33 m³ at a pressure of 135 kPa and temperature 40°C. Calculate the gas constant. 12 13 14 Calculate the volume of 2 kg of gas at 1 MPa and 600°C if Cy= 0.172 kJ/kg.K and Cp = 0.217 kJ/kg.K. In the cylinder of an air motor, the compressed air at the beginning of an expansion cycle has an internal energy of 500 kJ/kg and after expansion an internal energy of 150 kJ/kg. Calculate the heat flow from or to the sys- tem, when the work done by the air during expansion is 200 kJ/kg. Hint: AU = Ufinal - Uinitial- The heat loss in a certain non-flow process is 785 kJ. The internal energy in- creases by an amount of 522 kJ. How much work is being done? 11 A gas with a mass of 3 kg has a volume of 3.33 m³ at a pressure of 135 kPa and temperature 40°C.
