A sample of

\ce{H2}(g)

is contained in a cylinder with a moveable piston at an initial pressure of P, start subscript, 1, end subscript. The volume of the sample is increased from 3, point, 0, space, L to 6, point, 0, space, L while the temperature is held constant, as shown in the diagram below.

What is the final pressure in the cylinder?

(Choice A)
start fraction, P, start subscript, 1, end subscript, divided by, 6, end fraction
(Choice B)
start fraction, P, start subscript, 1, end subscript, divided by, 2, end fraction
(Choice C)
P, start subscript, 1, end subscript
(Choice D)
2, P, start subscript, 1, end subscript
