Answer:
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
[tex]\Delta U=Q-H-W\\\Rightarrow \Delta U=2750-1550-850\\\Rightarrow \Delta U=350\ J[/tex]
The change in internal energy of the system is 350 J
