Question

Try to explain to someone at home how ovens work to heat pizza, or to heat something. Use language you think will help the person really understand how molecules move as they are heated.

Answer 1

The heat is transferred from the metal rod to the pizza dough.

Step-by-step explanation:

An oven works on electricity. We know that according to the law of conservation of energy, energy is being transferred from one type to some some other type. It is not possible to create or form energy and also to destroy energy.

So in the oven when the oven is switched on to make a pizza, the electrical energy is converted into heat energy which bakes the pizza inside the oven.

When the oven is heated, the molecules inside the metallic rod vibrates and it transfers its kinetic energy to its neighboring atoms. This is how the entire rod gets heated up due to conduction from one point end to another. The heat is then flowed from the rod to the pizza through the surrounding air in the oven. The molecules in contact with the rod transfers the heat to the molecules in the surroundings. This process is called convection process.

This is how the heat is flowed and transferred from the rod to the pizza dough by conduction and convection process. Thus the temperature rises and it heats the pizza.
