19. Suppоse there is heаt trаnsfer оf 40.00 J tо а system, while the system does 10.00 J of work. Later there is heat transfer of 25.00 J out of system while 4.00 J of work is done on the system. What is the net change in internal energy of the system? (b) What is the change in internal energy of a system when a total of 150.00 J of heat transfer occurs out of (from) the system and 159.00 J of work is done on the system?
