4.3.3.1 Particle motion in gases

Content

The molecules of a gas are in constant random motion. The temperature of the gas is related to the average kinetic energy of the molecules.

Changing the temperature of a gas, held at constant volume, changes the pressure exerted by the gas.

Students should be able to:

explain how the motion of the molecules in a gas is related to both its temperature and its pressure

explain qualitatively the relation between the temperature of a gas and its pressure at constant volume.


WS 1.2 Use a variety of models such as representational, spatial, descriptive, computational and mathematical to solve problems, make predictions and to develop scientific explanations and understanding of familiar and unfamiliar facts.
