A system of one mole of a gas in a cylinder with movable piston absorbs 234 J of heat and is compressed by 534 J of work. ∆E for this system equals _____ J. (include the sign, e.g. +500 or -500)
Homework Answers
Heat (q) = +234 J
Work(w) = +534 J
According to first law of thermodynamics
∆E = q + w
= 234+534
= + 768 J
