Heat transfer
Conduction
What happens
Tightly packed atoms which vibrate most when heated this energy is passed atom by atom from tray to food
-
-
Method of transfer
Metals, good conductors of heat
Cooking pans, baking tins
Convection
-
What happens
- Faster they move the more collisions
4.Move from the cold top of the [an to the bottom which is a convection current as they lose energy when it is colder
- Amount of energy in water increases, water molecules move to a colder area colliding with particles and passing the energy to other molecules
-
- Conduction happens first through the pan
-
Radiation

-
Why is it important
-
-
When grilling the temperature is very hot so putting food close to the heat will make it burn easily
