HWPV Work previous 8 of 24 next PV Work The joule (J) is a unit of energy. Recall that energy may be converted between many different forms such as mechanical energy, thermal energy (heat), chemical energy, electrical energy and ght The mechanical energy produced by a systemacaled work when work is accomplished hough the changing volume of a gas, called PV work and is given bythe formula w = PV. where te is the work Piste el temal pressure, and is the change in volume lfthe volume change and pressure are in it and atmospheres respectively, then the work will have units of iter-almospheres, which can be converted to joules using the conversion factor 1 L-atm 101.3 J. is the work in joules, Fis the force in newtons, and disthe distance in Work can also be expressed as force multiplied by distance w=F×d, where meters. Note that 1 N-m 1J Part A Apiston has an eternal pressure of 10.0 atm. How much work has been done in joules Express your answer with the appropriate units. Hints the cylinder goestom a voume of 0. 140mers to 0.650 1ters? wValue Units My Answers Give UpExplanation / Answer
W = -Pext(Vf-Vi)
P = 10.0atm
Vi = 0.14 L
Vf = 0.65 L
put values in above expression
W = -Pext(Vf-Vi)
W = -10.0atm (0.65L - 0.14L)
W = -5.1 atm.L
W = -5.1 *101.33 J
W = -517 J
Answer: -517 J
