Work = -PdV = -4.5 atm*(5.50L-1.00 L) = -20.25 L*atm
Multiply by 101.325 to convert to J. Don't forget the negative sign to show work is being done on the atmosphere.
A cylinder within a piston expands from a volume of 1.00 L to a volume of 5.50 L against an external pressure of 4.50 atm.
Part A
How much work (in J) was done by the expansion?
Express the work to three significant figures and include the appropriate units.
