Pt. 1

Question

Gas in a container is at a pressure of 2.3 atm
and a volume of 6.1 m3.
What is the work done on the gas if it
expands at constant pressure to five times its
initial volume?
Answer in units of J

My wrong answer: 56.12

Pt. 2:
What is the work done on the gas if it is com-
pressed at constant pressure to one-quarter of
its initial volume?
Answer in units of J

Answer 1

I'll help with part 1

W=P(delta)V or work=pressure X volume change

W=(2.3 atm )(5 x 6.1)
W=70.15 J
