A gas is trapped inside a cylinder by a movable piston. The length of the gas column is 20 cm and the pressure inside the cylinder is p. [diagram: cylinder with movable piston, gas at initial pressure p, original position of piston, 20 cm, 50 cm] The piston is pulled out a distance of 30 cm, so that the length of the gas column is now 50 cm. The temperature of the gas does not change. What is the new pressure of the gas?

1. A0.40 p
2. B0.60 p
3. C1.5 p
4. D2.5 p
