| How does convection work? | When more energetic particles move from a hot region to a cooler region and take the heat energy with them. The air will rise when hot as it is less dense and sink when cool as it is more dense. |
| Explain how condensation happens. | When the gas cools the particles merge closer together, as they loose kinetic energy, and slow down. This turns the gas into a liquid |
| Explain evaporation. | The liquid particles heat up, giving them more energy, making them spread out turning the substance into a gas, allowing the particles to leave the liquid, taking heat energy which cools it down |
| Give four factors that will speed up evaporation. | Higher temperature Lower density Larger surface area Greater air flow over liquid |
| Give four factors that will speed up condensation. | Temperature of gas is lower Temperature of the surface the gas touches is lower Higher density Airflow is less |
