Exercise 3

Some gas occupies a volume of $2.0 \mathrm {~m} ^ { 3 }$ in a cylinder at a pressure of $200 \mathrm { kPa }$ . A piston, sliding in the cylinder, compresses the gas isothermally until the volume is $0.80 \mathrm {~m} ^ { 3 }$ . If the area of the piston is $240 \mathrm {~cm} ^ { 2 }$ , calculate the force on the piston when the gas is compressed.
