What energy transformation occurs in an oven?

In an oven, electrical or gas energy is transformed into heat energy, which is then transferred to the food placed inside the oven.

When an oven is turned on, the heating element inside the oven converts the electrical energy into heat. This heat is then circulated within the oven by a fan, ensuring an even distribution of heat throughout the oven cavity. In the case of a gas oven, the burner located at the bottom of the oven generates heat through the combustion of gas. This heat rises, heating up the air inside the oven and cooking the food.

The food placed inside the oven absorbs the heat energy from the surrounding hot air through the process of conduction. This causes the food to cook and eventually reach the desired temperature for consumption.

Therefore, the energy transformation that occurs in an oven involves the conversion of electrical or gas energy into heat energy, which is then transferred to the food through conduction.
