Engineering Thermodynamics A gas is compressed in a cylinder by a movable piston to a volume one half its original volume. During the process 300 kJ heat left the gas and internal energy remained same. The work done on gas in Nm will be 30 Nm 300 Nm 3000 Nm 300,000 Nm 30 Nm 300 Nm 3000 Nm 300,000 Nm ANSWER DOWNLOAD EXAMIANS APP
