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.
Imagine an ideal gas as a group of people dancing freely at a music festival where there's plenty of space for everyone to move around without bumping into one another - this represents low pressure. Also, since it's hot out (high temperature), people are more energetic and dance faster - representing higher molecular speeds.
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.
