Lesson details
Key learning points
- When it melts, a substance changes from the solid state to the liquid state.
- When it freezes, a substance changes from the liquid state to the solid state.
- At temperatures below its melting point, a substance is in its solid state.
- At temperatures above its freezing point, a substance is in its liquid state.
- The melting point and freezing point of a pure substance are the same temperature.
Keywords
Liquid state - Substances in the liquid state will take the shape of their container.
Solid state - Particles in a substance in a solid state are in a fixed position and can only vibrate.
Melting point - The melting point of a substance is the temperature at which it changes from a solid state to a liquid state.
Freezing point - The freezing point is the temperature at which a substance changes from a liquid state to a solid state.
Common misconception
Some students can't understand that substances can change from one state to another state.
Ensure that the language used is solid state, liquid state and gas state, not solid, liquid and gas.
