What you'll learn
The properties of matter and thermal energy.
Density and states
- Density = mass ÷ volume; particle arrangement in solids, liquids and gases.
Thermal energy
- Specific heat capacity and latent heat; internal energy.
- Gas pressure and temperature.
Exam tips
- Rearrange density correctly and watch units.
- Explain that latent heat changes state without changing temperature.
Common mistakes
- Confusing mass and weight.
- Forgetting temperature is constant during a state change.
