Here, students can learn more about how the microscopic behaviour of particles gives rise to macroscopic behaviour; they can...

Teaching Guidance 16-19

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

Lesson 16-19

This episode establishes the ideal gas law, and how to use it. NB many texts use the terms ideal gas and perfect gas as...

Lesson 16-19

This episode relates the gas laws to the behaviour of the particles of a gas.

Lesson 16-19

Energy must be transferred to (or from) a material to increase (or decrease) its temperature. Here is how to calculate how...

Lesson 16-19

Energy is involved in changes of phase, even though there is no change of temperature.

Lesson 16-19

This episode introduces the mechanical properties of materials: often an important consideration when choosing a material for...

Lesson 16-19

The Young modulus is often regarded as the quintessential material property, and students can learn to measure it. It is a...

Lesson 16-19

A stress-strain graph includes a great deal of information about a material. Your students may need to learn to extract this...

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...

Glossary Definition 16-19

A stretched or compressed material will experience strain. If the material is of uniform cross-sectional area, strain...

Glossary Definition 16-19

A stretched or compressed material will experience stress. Stress is a measure of the force that the material is experiencing...
