An Ideal gas enters a throttle at 1.07 bar and 14oC. The gas emerges at a pressure of 0.3 bar and a temperature of 12oC. The mass flow rate of gas is 3 g.s-1, and its specific heat capacity at constant pressure (Cp) is 1.15 kJ.kg-1.K-1.

Assuming steady-state, steady-flow (SSSF) operation, calculate the rate of heat transfer (in J.s-1) into the gas as it flows through the nozzle.
