Published on 2018 July 26th

Experiment with some gas trapped in an air chamber. Notice how the gas is made of particles. Investigate the speed and collisions of the air particles. Discover what happens to them as you change the temperature. Observe how this affects the properties of the gas. For example, measure the change in pressure as you heat the gas. This learning object is one in a series of four objects.
1. Students describe the particle nature of gases, including the characteristics of the particle motion.
2. Students use a particle model to explain gas pressure.
3. Students describe the effects of temperature changes on particle motion, and explain how this affects pressure.
