"PV Work": A piston weighing

2kg

is set into a cylinder that is

0.10m

in diameter and

1m

high which is\ filled with an ideal gas. The force on the piston due to gravity moves the piston to

20cm

above the bottom\ of the cylinder, at which point the pressure of the gas just balances the weight of the piston and it stops\ moving and is at mechanical equilibrium. Assume that

P_(ExT)=0

bar above the piston so that only the weight of\ the piston on the gas keeps the gas from expanding. More gas is injected very slowly into the cylinder below
