Question

A gas is compressed and during this process the surroundings do 43.3 J of work on the gas. At the same time, the gas absorbs

Answer 1

Answer #1

W = -43.3 J
Negative because work is done by the gas

Q = +281 J
Positive because system absorbs heat

Use:
Delta E = Q + W
= 281 J - 43.3 J
= 237.7 J

Answer: 238 J

Answer 2
