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)A. `-20.41 J`B. `+19.41 J`C. `-1970 J`D. `-2070 J`

1.	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)A. `-20.41 J`B. `+19.41 J`C. `-1970 J`D. `-2070 J`
Answer» Correct Answer - C `w = - P_(ext) Delta V = - (20.4 - 1.0) = - 19.4 L` atm `= -19.4 xx 101.4 = - 1967 J`
