3.31 A closed system of mass

3kg

undergoes a process in which there is a heat transfer of

150kJ

from the system to the surroundings. The work done on the system is

75kJ

. If the initial specific internal energy of the system is

450k(J)/(k)g

, what is the final specific internal energy, in

k(J)/(k)g

? Neglect changes in kinetic and potential energy.
