# Problem: A cylinder equipped with a piston expands against an external pressure of 1.51 atm. If the initial volume is 0.505 L and the final volume is 1.280 L, how much work (in J) is done?

###### FREE Expert Solution

$\overline{){\mathbf{∆}}{\mathbf{E}}{\mathbf{=}}{\mathbf{q}}{\mathbf{+}}{\mathbf{w}}}$

where w is work

$\overline{){\mathbf{w}}{\mathbf{=}}{\mathbf{-}}{\mathbf{P}}{\mathbf{∆}}{\mathbf{V}}}$
