Energy transfer by heating 0.0 / 5 ? PhysicsEnergyGCSEAQA Created by: emmajane_Created on: 27-02-14 20:01 CONDUCTION- What causes heat? The kinetic energy of particles as they vibrate. 1 of 8 CONDUCTION- What are the effect does heat have on particles? Particles vibrate(kinetic energy) Bump into neigbouring particle passing enery along 2 of 8 CONVECTION- Why do hot liquids and gasses rise? They expand and become less dense. 3 of 8 CONVECTION- Why do cold liquids and gasses sink? They contract and become less dense 4 of 8 CONVECTION- In which states does convection occur? fluids- liquids and gasses 5 of 8 EVAPOURATION- Name 3 ways to make liquids evapourate faster Increase surface area, Increase temperatre, pass air over 6 of 8 EVAPOURATION- how does evapouration work? Particles leave the surface and overcome the attraction of the other liquid particles. 7 of 8 CONDENSATION- what causes condensation? cooling 8 of 8
