What happens when particles are under cold water compared to hot?

• The particles move towards the hot and begin to rise

• The particles stay in place and do not move

• The particles begin to rise under the cold

Which type of material rises?

• Material that is more dense

• Material that is less dense

• The density does not determine if particles will rise or fall
