Asteam engine takes in 2,750 j of energy as heat, gives up 1,550 j of energy as heat to its surroundings, and does 850 j of work. what is the change in the internal energy of the engine

350 J

Explanation:

Q = Input heat of the steam engine = 2750 J

H = Heat energy given of to the surroundings = 1500 J

W = Work done by the system = 850 J

The energy which the system possesses is known as internal energy

Change in internal energy is given by

The change in internal energy of the system is 350 J
