Published on 2018 July 25th

Experiment with gas trapped in an air chamber. Change the size of the chamber, add or remove gas and notice how the gas pressure changes. For example, double the pressure by halving the volume. Control the pressure by balancing the volume of the chamber with the number of gas particles it contains. This learning object is one in a series of four objects.
1. Students predict the effect of change in volume on the pressure of a gas.
2. Students predict the effects of changes in particle numbers on the pressure of a gas.
3. Students interpret changes in gas pressure in terms of frequency of particle collisions.
