Question

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

Answer 1

Answer:

by Boyles law we know that pressure is inversely proportional to volume.

if pressure is decreased by half then volume become twice.

Answer 2

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.

P1 ⋅  V1 = P2 ⋅  V2

If the final pressure of a gas is half of the initial, the volume must double if temperature is to remain the same.
