If the volume of a confined gas is doubled while the temperature remain constant, what change (if any) would be observed in the pressure

The gas will obey Boyles Law:

P1 V1 = P2 V2 where P1 and V1 are the original pressure and volume and P2 and V2 are the new values.

If V2 = 2V1 (given) then:

P1 V1 = P2 * 2 V1

P2 = P1 V1 / 2V1

P2 = P1 / 2

In other words the pressure is halved. (answer).

Halfed
