When ideal gas does not exist then why laws were stated?

Question

anonymous · Answer

because all real gases don't behave same way

Please post physics questions in the physics section.
Thanks.

We idealize for situation all the time: ignoring air resistance, imagining perfect springs and strings, etc. all in the sake of trying to see the basic mathematical structure of the problem. You can incorporate the more "realistic" details later.

Lol !!! Nice question.. 

For comparing things u need some common ground. Well you can say this is a reference or base to compare all other gases.. 

gotta ??

for instance, in projectile motion we usually ignore air resistance at first, in order to better understand the underlying structure of the problem (how we can separate the vertical and horizontal components).
we can incorporate air resistance much more easily once we understand the simplified way first.

See,
we make certain assumptions to know the behavior of something..

Like the Letter A,
one who has discovered it could make this symbol as B, U L like that..

But we assume that the first letter of English alphabet will be drawn like A..

If we didn't assume that then there was no English in the World..

So,laws are defined and stated and assumptions are made to know everything about something in this world..

And you must know that anything in this world is not perfect or we can say ideal..
