General Gas equation
PV=nRT
which explains all gas laws and do you know gases which obey all gas laws are ideal..
Ok, what is an ideal? No one is perfect so how do you think gases are ideal 😄 it is just an hypothetical concept.
So come to the point which gas laws are explained by ideal gas equation
Boyles law
V=K/P
PV=nRT
V=nRT/P
In Boyles law no of moles and T are constant and R is already a contant so
V=K'/P so Boyles law is explained by ideal gas equation
Likewise Charles law, avogadros law all these are explained by this simple equation.
Comment if you know about charles law and avogadros law.
