Question

Can gas pressure increase by decrease in the volume

Answer 1

no the pressure of the gas can not be increased by decreasing volume .

Answer 2

Answer:

Because the volume has decreased, the particles will collide more frequently with the walls of the container. ... More collisions mean more force, so the pressure will increase. When the volume decreases, the pressure increases. This shows that the pressure of a gas is inversely proportional to its volume.
