A heat pump takes in 300 J of heat from a lower temperature reservoir in each cycle and uses 150 J of work per cycle to move the heat to a higher temperature reservoir how much he is released to the higher temperature reservoir in each cycle?

First answer marked as brainiest which is the correct equation describing the first law of thermodynamics? a) when the internal energy of a system changes, it equals the amount of heat added plus the work done. b) when work is done by the piston, it is equal to the heat added plus the change in internal energy of the system. c) when heat is added to the system, it is equal to the amount of work done by the piston plus the change in internal energy of the system.
