Heat convection occurs in gases and liquids will both expand
Glass, wood and plastic are all poor conductors of heat. Your web browser does not have JavaScript switched on at the moment. Metals have free electronsthe free electrons gain extra kinetic energy at the warm end of the material.
This is because the particles in liquids and gases move faster when they are heated than they do when they are cold. Metals are very good conductors of heat energy because there is a second process at work. Glass, wood and plastic are all poor conductors of heat. They diffuse to cooler areas where they collide with the particles in the material transferring their kinetic energy. Convection Liquids and gases are fluids.
Energy can be transferred by conduction, convection, evaporation and condensation. As a result, the particles take up more volume. Energy transfer by heating. The denser cold liquid or gas falls into the warm areas.

This leaves the less energetic particles still in the liquid and so the liquid is cooler. Metals have free electronsthe free electrons gain extra kinetic energy at the warm end of the material. The more dense cold liquids and gases sink down through the less dense warm liquids and gases. Is the movement of thermal energy through a material without the particles in the material moving.
Metals are very good conductors of heat energy because there is a second process at work. Glass, wood and plastic are all poor conductors of heat. Heat is the kinetic energy of particles as they vibrate.
This leaves the less energetic particles still in the liquid and so the liquid is cooler. They collide with their neighbours and so the energy is passes from one particle to another through the material. Print Science Energy transfer by heating. This is because the particles in liquids and gases move faster when they are heated than they do when they are cold. Glass, wood and plastic are all poor conductors of heat.
