### Ideal Gases

How do we know if a gas is ideal? Do we just assume it is in most scenarios?

I believe the general assumption is that a gas acts more "ideal" at higher temperatures and at lower pressures. I think most of the problems we will be given deal with ideal gases unless otherwise stated.

### Re: Ideal Gases

In reality, no gas is ideal. An ideal gas is a theoretical gas which we give certain properties which allows us to simplify calculations. We can use these calculations as well as correction factors to make calculations about real gases. The ideal gas law is used to make calculations about ideal gasses. The Van der Waals equation uses correction factors to account for the "un-idealness" of gasses.

### Re: Ideal Gases

An ideal gas is a theoretical idea that the gas is in a simple form so that it allows for easier calculation. I think most problems that we are given will only consist of ideal gases.
