Find net heat transfer for change-specific internal energy
2.6 kg of air in a stationary box undergo a process that results in 22.3 kJ of work being done by the air (say there was a combustion process). Find the net heat transfer for the process if the change in specific internal energy is +55 kJ/kg.
