The volume of a gas is increased from 15 l to 45 l while the temperature is held constant. the pressure of the gas will decrease by a factor of?

It decreases by a factor of 1/3.

OK; Boyle's law states that the pressure of a gas and the volume it occupies are inversely proportional, so that means.

V

∝

1

P

Therefore, if the pressure increases by a factor of 3, then at constant temperature, then the volume would decrease by a factor of 1/3, (cut in third).

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
