Calculate the work done when the volume of a cylinder is increased by 90.0 L against the atmospheric pressure. Think about the upward movement of a piston as it expands the volume of a cylinder.

I am actually an AP Chemistry student and am supposed to do this problem using unit analysis as I am not taking AP Physics. However, I have taken Grade 11 Physics.

Thank you for your help!

My Work:

Since 1 L = 0.001 m^{3}, then 90.0 L = 0.0900 m^{3}.

Since 1 Pa = 1 N/m^{2}, then 1.013E5 Pa = 1.013E5 N/m^{2}.

In order to get Nm = J = work:

1.013E5 N/m^{2}x 0.0900 m^{3}= 9,117 Nm = 9117 J = 9.12 x 10^{3}J.
