Temperature vs Heat

• All matter is made of tiny particles called molecules which are always moving.

• Temperature is a measure of how much they move.

• Heat is a measure of how this movement energy transfers between different things.

• Fridges work by removing heat from the chamber rather than 'adding cold'

• Sweat takes heat away from the body, transferring it to the air

• Hot coffee heats ice cubes in an iced latte, melting them

​Heat moves through direct contact between objects, like a spoon getting hot in a cup of tea.

Conduction

​Heat moves through fluids (liquids or gases) by currents, like warm air rising and cool air sinking.

Convection

​Heat is transferred through electromagnetic waves, like the warmth you feel from the sun.
