A gas in a piston-cylinder assembly undergoes two processes in series.
From state 1 to state 2 there is energy transfer by heat to the gas with a magnitude of 375 kJ, and the gas does work on the piston with a magnitude of 685 kJ.
The second process, from state 2 to state 3, is a constant pressure compression at 410 kPa during which there is a heat transfer from the gas with a magnitude of 475 kJ.
The follow data are also known:
U1 = 2030 kJ and U3 = 3520 kJ.
A) Neglecting changes in kinetic and potential energy, calculate the change in volume of the gas during process 2-3 in m^3.
