A mass of ideal gas in a closed piston-cylinder system expands from 427 °C and 16 bar following the process law, pv1.36 = Constant (p times v to the power of 1.36 equals to a constant). For the gas, initial : final pressure ratio is 4:1 and the initial gas volume is 0.14 m³. The specific heat of the gas at constant pressure, Cp = 0.987 kJ/kg-K and the specific gas constant, R = 0.267 kJ/kg.K. Determine the change in total internal energy in the gas during the expansion. Enter your numerical answer in the answer box below in KILO JOULES (not in Joules) but do not enter the units. (There is no expected number of decimal points or significant figures).
