The change in the internal energy of a system that releases 2,500 J of heat and that does 7,655 J of work on the surroundings is ________ J.
Added by Mohamed H.
Step 1
In this case, the system releases heat, so Q is negative. The system does work on the surroundings, so W is positive. So, Q = -2,500 J and W = 7,655 J. Show more…
