Heat is a form of energy or power.
We can feel heat from sources like the sun or a fire; from friction when we rub our hands together; from hot water from a tap; and from appliances such as heaters, toasters and electric blankets.
You will notice that most pots have plastic handles.
This is so we can hold the pot and not burn our hand.
This warm soup is lighter and moves up to the top where the soup is cooler.
The cooler soup moves down.
The warmer and cooler molecules and atoms mix until the temperature is the same throughout.

Warm air is lighter than cool air so it rises.
Cool air comes down to take its place. It gets warmed and rises.
The movement of the liquid or gas is called a convection current.
