A popular game is ''splatball'', where people use pressurized CO2 cartridges to shoot paint-filled plastic balls at targets and at each other. A typical splatball gun takes a 1.00 L CO_(2) catridge filled to 300 PSI pressure. How many work is done as this cartridge is discharged (to atmospheric pressure) when the gun is fired ? (14.7 PSI = 1 atm)

Answer» `-20.41 J` `+19.41 J` `-1970 J` `-2070 J` Solution :`w = - P_(EXT) DELTA V = - (20.4 - 1.0) = - 19.4 L` atm `= -19.4 xx 101.4 = - 1967 J`
