what they do

• when we heat a metal pan on a hob, or baking tin in the oven, it quickly heats up and transfers heat energy to the food inside this process is called conduction
• the atoms that make up metals are tightly packed together in a lattice
• as the heart energy from the cooker hob or oven is transferred into a pan, it makes the metal atoms vibrate
• as they vibrate, they knock against adjoining atoms and pass on the heat energy, then they pass it on to others, and so on
