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?
