    Question: The volume of an ideal gas is compressed from 4.0L to 2.0L under a constant pressure of 850 Pa. How much work is done on the gas?

    2. Relevant equations

    W=-P(Change in volume)

    1.Don't forget the unit of work.
    2.Do you think that the work done on the gas is negative or could it be positive?
