Pt. 1
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 onequarter of
its initial volume?
Answer in units of J

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
