Evaporation,Condensation and factors affecting heat transfer 3.0 / 5 based on 1 rating ? PhysicsEnergyGCSEAQA Created by: korinCreated on: 22-05-13 16:53 What forces are between particles? Forces of attraction 1 of 7 How does evaporation occur? Particles absorb heat energy causing them to move faster. Some of the particles escape from the surface. The remaining liquid is cooler. 2 of 7 What changes the speed of evaporation? Bigger surface area, higher temperature and/or wind/fan/draft. 3 of 7 For example if you hang up a wet t-shirt, why will it speed up evaporation? It is spread out so there is a bigger surface area and increase the rate of evaporation 4 of 7 How does condensation occur? Particles los heat energy making them move slowly making them more closer together (Condensing from a gas to a liquid) 5 of 7 How can you increase heat loss? Increase surface area, change the material the object is on and change the material of the object. 6 of 7 How does an elephant,a desert fox and an arctic fox adapt to their environment? Elephant-Big and flat ears allow them to lose heat, Desert fox- large surface area ears-lose heat, Arctic fox- Small surface area of ears-keep heat in 7 of 7
