Gas Law
This article explains about the gas law

Application of these laws will also be explained

Introduction
Matter exist in three forms i
...
liquids solids and gases
...
Gas as matter has got properties
among them is that gases have indefinite volume, indefinite shape and it has got definite mass
...
Likewise, if the volume of a gas is reduced then
the pressure increase only when the absolute temperature
...

Boyle`s Laws
It deals with the relationship between pressure and volume of a fixed mass of a gas when
temperature is kept constant
...




The pressure in gases is as a result of collision of the gas molecules with the walls of a
container containing the gas

P1V1=P2V2



A graph of pressure against 1/v is a straight line graph through the origin
...
In the law Charles came up with a conclusion that there is a
relationship between temperature and volume when the absolute temperature is kept constant

Ideal gas-It is a gas whose volume is theoretically zero
...

Law
The law deals with the variation in the volume of a fixed mass of a gas with respect to changes in
temperature and pressure

VαT/P Introducing constant K in the expression
V=KT/P
PV=KT
PV/T=k
When P1 changes to P2 , V1 to V2and T1 to T2 then:
V1P1/T1=V2P2/T2 (this is an ideal gas equation)
Applications of Gas Laws


Inflating tires, balls and balloons depends on the prevailing temperature conditions
...




Regulations of pressure in an aircraft for comfortable in flight environment at high altitude
...
It is clear that when temperature
is increased and the volume is kept constant pressure is increased
...
This is due to increased kinetic energy which in turn
exerts pressure on the walls of the containers they are held in
