The δe of a system that releases 12.4 j of heat and does 4.2 j of work on the surroundings is __________ j.
Added by Ashley S.
Step 1
In this case, the system releases 12.4 J of heat, so q = -12.4 J (negative because heat is released). The system does 4.2 J of work on the surroundings, so w = -4.2 J (negative because work is done on the surroundings). Show more…
