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.
