What is the relationship between the combined gas law and the ideal gas law?
The Combined Gas Law is a combination of Boyle's, Charles' and Gay-Lussac's laws.
The Combined Gas Law joins these to make
The Combined Gas Law should also include Avogadro's Law: "The volume of a gas is directly proportional its number of moles".
Then the Combined Gas Law becomes
If we call the constant
When we rearrange this equation, it becomes
We call this equation the Ideal Gas Law.
