Convection. Conduction and Radiation

Question 1

Convection example

Answer 1

The Bunsen burner heats up the water.The warm water expands and becomes less dense which means it rises.Cooler,more dense water sinks to replace the warm water and a convection currant is set up.

Question 2

Conduction Def.

The way heat travels through solids

Question 3

Answer 3

You put a metal spoon in hot soup and leave it in there for a few minutes. After a while the heat will got through the spoon and the spoon will become really hot. This shows that metals are really good conductors. Fluids, however, are not good conductors.
