- Convection, Condensation and Evaporation
- When more energetic particles move from the hotter to cooler region and take their heat energy with them
- Convection currents
- About changes in density, heated particles with lots of energy rise, and then when they cool and lose energy, become more dense, then they fall
- Condensation- gas turns to liquid
- As a gas cools, its particles slow down and lose kinetic energy, and the attractive forces between the particles pull them closer together, make it a liquid
- Evaporation - liquids turns to gas
- Particles escape from a liquid by having enough inetic energy to overcome attractive forces
- The fastest particles are most likely to escape,, so when they do, the average energy speed and kinetic energy of the remaining particles decreases, so the temperature falls
- Particles escape from a liquid by having enough inetic energy to overcome attractive forces
