Solids, Liquids And Gases: Units
Muhtasari
Every equation in physics only works when the quantities going into it are measured in the right units. Mixing up grams with kilograms or centimetres with metres is one of the fastest ways to lose marks on a calculation, and it happens more often than you might expect.
This lesson gives you the complete set of SI and derived units that appear across the Solids, Liquids and Gases section of the Edexcel IGCSE. You will practise converting between related units, learn how to spot when a value needs converting before substitution, and build the reflexes that keep unit errors out of your exam work.
Malengo
- Use the following units: degree Celsius, Kelvin (K), joule (J), kilogram (kg), kilogram/metre3 (kg/m3), metre (m), metre2 (m2), metre3 (m3), metre/second (m/s), metre/second2 (m/s2), newton (N) and pascal (Pa)
- Use the following unit: joules/kilogram degree Celsius (J/kg C)
