Ideal Gases

Definition

An ideal gas is a theoretical gas composed of randomly moving, non-interacting point particles. Real gases approximate this behavior under low pressure and high temperature conditions.

Real Gas: A real gas does not follow all assumptions made by ideal gases due to intermolecular forces; think about if our music festival got crowded or cooler - people would start interacting more (bumping into each other) and moving slower.

Gas Laws:

These are the laws that describe how gases behave, like Boyle's Law or Charles' Law; they're like the rules of our music festival - for example, as more people come in (increase in pressure), you have less space to dance (decrease in volume).

Avogadro's Law:

This law states that equal volumes of all gases at the same temperature and pressure contain an equal number of molecules; it's like saying no matter what type of music is playing, if the festival grounds are equally filled with people, there will be the same number of dancers.
