a gas is enclosed in a cylinder fitted with a piston. the volume of the gas is 2 L at 1 atm pressure. the piston is moved to increase the volume to 6 P. which of the following is a reasonable value for the pressure of the gas at a greater volume and why?
1) 6.00 atm
2) 12 atm
2) .333 atm

Firstly, I assume you mean 6 L for the increased volume
Pressure and volume are inversely related (Boyle's Law)
So if the volume is increased 3 fold, the pressure becomes one third of previous
The answer is 0.333 atm.

Absolute Pressure decreases with increase in volume at constant temperature. (Boyle's Law).
The only one to agree with this is No. 3 answer...0.333atm.
