Temperature & Speed
- Imagine molecules of gas that are free to move around in a box
- The molecules in the gas move around randomly at high speeds, colliding with surfaces and exerting pressure upon them
- The temperature of a gas is related to the average speed of the molecules:
- The hotter the gas, the faster the molecules move and vice versa
- Hence, the molecules collide with the surface of the walls more frequently
Gas molecules move about randomly at high speeds
- This is because their kinetic energy increases
