Remain the same

Be reduced to one half its original value

None of the above

Detailed explanation-1: -If the volume of a confined gas is doubled (without the addition of more gas), the pressure will (assume the temperature remains constant). be reduced to one-half its original value. If the temperature of a confined liquid is held constant and its pressure is tripled, the volume will? remain the same.
Detailed explanation-2: -At the molecular level, the pressure of a gas depends on the number of collisions its molecules have with the walls of the container. If the pressure on the piston is doubled, the volume of the gas decreases by one-half.
Detailed explanation-3: -The volume of a confined gas can be reduced, at constant temperature, by increasing the pressure on the gas. The change in volume may best be explained by the fact that the gas molecules: a) take up space.
