Physics: Solids, Liquids And Gases: Units
Overview
Solids, liquids and gases are described by quantities that most other physics topics never touch: volume in cubic metres, pressure in pascals, and temperature on two different scales at once. Getting those units right is half the battle in this section.
In this lesson you will meet each unit used in solids, liquids and gases, see how the derived ones are built from the base units, practise the awkward conversions for area and volume, and learn to use units as a check that your working is sound.
Objectives
- Use the following units: degree Celsius, Kelvin (K), joule (J), kilogram (kg), metre (m), metre2, metre3, metre/second (m/s), metre/second2 (m/s2), newton (N) and pascal (Pa)
