Question

A gas in a cylinder has a pressure of 235 kpa at a volume of 5.00 l the volume is reduced to 1.25 l the temperature does not change find new pressure of the gas

Answer 1

pressure when the volume is reduce to 1.25 L is

`P_(2) =940` kpa

Step-by-step explanation:

The temperature doesn't change so is constant so, the equation of the law of gases use is :

`T= Constant\\ P_(1)*{v_(1)=P_(2)*{v_(2)`

Law of Boyle of gases

`P_(1)=235 kpa\\{v_(1)=5L\\`

`{v_(2)=1.25L`

`P_(2)= (P_(1)*v_(1) )/(v_(2)) \\P_(2)= (235 kpa*5L )/(1.25L)=940 Kpa`
