Problem 89..4 kg of gas occupying 1.2 m³ had an initial temperature 18 deg * C .I was then heated at constant volume until its temperature becomes 120 deg * C How much heat was transferred to the gas? What was its final pressure? Take R = 0.287 kJ/kg K and C_{P} = 1 1.005 kJ/kg K.... 4 kg of gas occupying 1.2 m³ had an initial temperature 18 deg * C .I was then heated at constant volume until its temperature becomes 120 deg * C How much heat was transferred to the gas?
