Question

Calculate the work done if a gas is compressed from8.8 L to 3.3 L atconstant temperature by a constant pressure of 2.7 atm, and give your answer in units of joules. (1 L· atm = 101.3 J)
____________J

Explanation / Answer

work done by gas = P(V2 - V1)                            = -2.7 x(8.8 - 3.3)x 101.3 J                              = 1504.305 J as the gas is compressed work is done on the gas to doso. also we can see that total work calculated is negative so, work is done on the system by the surrounding.
