Name 2 of the 4 Kinetic Molecular Theory of Gases
1. Gases are composed of tiny particles that are separated by large distances.
2. Gas particles are constantly moving, experiencing collisions with other gas particles and the walls of their container.
3. The velocity of gas particles is related to the temperature of a gas.
4. Gas particles do not experience any force of attraction or repulsion with each other.
