According to Boyle's Law, a gas has a volume of 5.0 L at a certain pressure. How must the pressure be changed to double the volume of the gas at constant temperature?

The pressure must be halved.
The pressure must be quadrupled.
There is not enough information to decide.
The pressure must be doubled.

  1. Boyle's Law says volume and pressure are inversely proportional. In practical words that is this.
    Volume goes up then pressure goes down or
    Volume goes down then pressure goes up.

    Or you can use p1v1 = p2v2
