Gas in a container is at a pressure of 1.20 atm and a volume of 8.00 m3. (a) What is the work done by the gas if it expands at constant pressure to twice its initial volume? wrong check mark J (b) If it is compressed at constant pressure to one quarter of its initial volume? I am using the equation W=P(Vf-Vi) The change in volume would 8.00 m3? The pressure is in atm and I'm not sure what it should be converted to... is any of this correct?
