A hypothetical gas whose molecules occupy negligible space and have no interactions, and that consequently obeys the gas laws exactly.
According to Boyle's law
V∝1/P
and According to Charle's law
V∝T
According to Avogadro's law
V∝n
Joining all the above equations we get,
V∝nT/P
V= constant nT/P
V= RnT/P
PV=nRT
This is called an Ideal gas equation or general gas equation.
Where,
R=General gas constant=8.314 J/mol. K
P= pressure
V=volume
T=temperature
n=number of molecules
Thank you!
