Heating and cooling

Solid

In a solid the particles vibrate an around a fixed position. There is a strong force of attraction between each particle and they are very close together

Liquid

In a liquid the particles are fixed close together but can move in any direction. They won’t keep a fixed shape like solids do

Gases

In a gas the particles are very far apart and move quickly in all directions. Often collide with each other and can be easily squashed

Conduction

When heat energy is passed through a material from one particle to the next .

What happens in conduction

The particles at the warm end move faster and hit the particles next to them causing them to move faster. In this way heat is transferred by the vibrational movement of atoms

Conductors

Materials better at conducting in general metals are best

Insulators

Materials which are very poor conductors called thermal insulators, wood cortan cork and good insulators

Evaporation

Water will evaporate because the water molecules have enough energy to escape from rest of the water
