Pressure Law

Demonstration: A quick, dramatic demonstration to show the pressure of a fixed volume of gas increases with temperature.

Practical Activity 14-16

Demonstration: Measuring the change in pressure when air is heated at constant volume.

Practical Activity 14-16

Class practical: This experiment leads to the concept of absolute zero. Students investigate the effect of temperature on the...

Practical Activity 14-16

The experimental graph of pressure against temperature is likely to be straight enough to justify asking whether the plotted...

Teaching Guidance 14-16

This episode looks at Brownian motion as evidence for the particulate nature of matter, and the macroscopic gas laws.

Lesson 16-19

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...
