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

Answer:

pressure when the volume is reduce to 1.25 L is

$P_{2} =940$ kpa

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

$P_{1}=235 kpa\\{v_{1}=5L$

${v_{2}=1.25L$

$P_{2}= \frac{P_{1}*v_{1} }{v_{2}} \\P_{2}= \frac{235 kpa*5L }{1.25L}=940 Kpa$
