Work and Heat in Thermodynamic Processes

  1. Jan 9, 2006 #1
    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?

    Convert atmospheres to Pascals, the standard SI unit of pressure. (1 Pa = 1 N/m^2) Then your work will be in Joules.
