✔ 最佳答案
Change in internal energy of the system= (Energy flows into the system) - (Work done by the system on its surroundings)
= (300 J) - (1000 J)
= -700 J
(The negative sign indicates that internal energy decreases.)

I think it decreases by 700 jules because that is the net loss of energy. Good luck!
