Answer to Question #247523 in General Chemistry for Jas

Question

What is the work done by a system when it absorbs 50J of heat and gains 24 J of energy?

Answer 1

$q = 50J\\ ∆U = 24J\\ w =\ ?$

$∆U = ∆q - w\\ w= ∆q - ∆U\\ w = 50- 24 = 26 J$

$\therefore$ The system expands and the work done is 26J$.$
