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.
In a kitchen, an oven is a major source of both heat and fuel. Ovens work by converting electrical energy or gas into heat, which is used for cooking food. There are primarily two types of ovens: electric ovens and gas ovens. In an electric oven, heating elements inside the oven cavity convert electricity into heat. In a gas oven, a gas burner produces a flame that heats the oven.
The oven provides consistent, controlled heat, making it suitable for baking, roasting, and other cooking methods that require uniform and sustained temperatures. This makes it a central piece of equipment in most kitchens for preparing a wide variety of meals.
Other kitchen appliances mentioned, such as the deep fat fryer, hot plate, and dishwasher, serve different functions but do not serve as both a heat and fuel source in the same way. A deep fat fryer generates heat using an electric element or gas to heat oil, which is used for frying food. However, it does not provide an ambient heat source in the kitchen like an oven does. Similarly, a hot plate can generate heat through electricity or gas, but it is usually limited to small-scale cooking rather than the range of cooking styles provided by an oven. A dishwasher, on the other hand, is primarily used for cleaning dishes, not for generating heat for cooking purposes.
Therefore, while each appliance plays an important role in a kitchen, the oven stands out as a primary source of both heat and fuel for cooking.
