If the pressure on a gas is decreased by one-half, how large will the volume change be?

Apr 6, 2016

Answer:

The final volume is double the initial volume.

Explanation:

You can use Boyle's law, which states that pressure is inversely related to volume when other variables are held constant.
$P 1 \cdot V 1 = P 2 \cdot V 2$
If the final pressure of a gas is half of the initial, the volume must double if temperature is to remain the same.
