What happens

to the pressure of a gas if the

volume of gas is tripled at a

constant temperature?

The pressure will decrease 3 times

Explanation:

In this case, we apply Boyle Mariotte's Law: for a given gas mass at constant temperature, the pressure and volume vary inversely proportionally (the higher the pressure, the lower the volume and vice versa).

By increasing the volume 3 times, the pressure decreases 3 times to maintain the relationship: P1xV1 = P2xV2
