Which of the following is a source of heat & fuel in a kitchen?
Deep fat fryer
Hot plate
Oven
Dishwasher
The correct answer and explanation is:
The correct answer is Oven.
An oven is a common kitchen appliance that serves as a source of both heat and fuel for cooking. It uses electrical or gas energy to generate heat, which is then distributed evenly to cook food. The heat source can vary depending on the type of oven. For instance, a gas oven uses a burner to produce heat, while an electric oven relies on heating elements that heat up when electricity passes through them.
Ovens are versatile in the kitchen and can be used for a wide range of cooking methods, such as baking, roasting, grilling, and broiling. The oven’s heat is contained within an insulated chamber, which helps maintain consistent temperatures for the cooking process. The fuel (gas or electricity) is the driving force behind this heat, allowing the oven to function efficiently.
A deep fat fryer provides heat, but it is specifically designed for frying food by submerging it in hot oil. While it serves as a heat source, it is not typically a “fuel” source like the oven because it relies on the oil for heat transfer.
A hot plate can be used for heating but is generally a portable cooking device rather than a primary heat source in a kitchen. It does not use its own fuel; instead, it is powered by electricity or gas.
A dishwasher is a kitchen appliance used for cleaning dishes and does not provide heat for cooking. While it uses hot water to clean dishes, it does not serve as a source of cooking heat or fuel.
Thus, an oven is the most accurate answer as it combines both heat and fuel for food preparation.
