Convection, Evaporation & Condensation
Fichas del conjunto (5)
- 1How 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.
- 2Explain 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
- 3Explain 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
- 4Give four factors that will speed up evaporation.Higher temperature
Lower density
Larger surface area
Greater air flow over liquid - 5Give 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
