Calculating Work Done by Ideal Gas: Qualitative Pressure vs Volume

[kawafis44]

1. Calculate the work done by 1 mole of ideal gas in expanding adiabatically from V_1 to V_2 (volumes). Make a qualitative figure of pressure changes as a function volume changes p=p(V).

I will be very grateful for solving this problem because I spent so much time on it and I still do not know how to do it.
Thank you in advance!

The work done by the gas can then be determined. If the final volume is less than the initial, then work is done on the gas and the work will be negative.
