Work Done by Gas

Work, abbreviated as W, is the product of force and distance but for gas work is pressure and the volume during the change in volume.  When a gas expands it does work on its surroundings.

 

Work Done by gas formula
\(W \;=\; p  \; V \)     (Work Done by Gas) \( p \;=\; W \;/\; V \) \( V \;=\; W \;/\; p \)
Symbol	English	Metric
\( W_{net} \) = Work	lbf - ft$	$J$
$ p $ = Pressure (psi)	$lbf\;/\;in^2$	$Pa$
$ V $ = Volume	$ft^3$	$m^3$
