Demonstration: A quick, dramatic demonstration to show the pressure of a fixed volume of gas increases with temperature.
Demonstration: Measuring the change in pressure when air is heated at constant volume.
Class practical: This experiment leads to the concept of absolute zero. Students investigate the effect of temperature on the...
The experimental graph of pressure against temperature is likely to be straight enough to justify asking whether the plotted...
This episode looks at Brownian motion as evidence for the particulate nature of matter, and the macroscopic gas laws.
A fluid exerts a force normal to any surface with which it is in contact, for a planar surface the pressure is given by the...
