Here are some properties of ideal gases:
- Inert: Ideal gases are assumed to not react with each other.
- Elastic collisions: Ideal gases collide with the container's walls elastically, meaning they don't lose energy after collisions.
- Take the shape of their container: Ideal gases take the shape of their container, so the volume of the container is the same as the volume of the gas.
- Follow the ideal gas law: The ideal gas law is
PV= nRT - Compressibility factor of 1: The compressibility factor of an ideal gas is exactly 1.
