The microwave oven is a heating tool that we use every day, and it was first used for something

At first, I have to help heat the dishes. You can cook something.

It was first used to heat food.

It was first used to heat meals, and later it was also used to bake.

The microwave oven is still used to heat food in the morning.

At first, it was just to heat up the meal, but now it's time to make cakes and let him bake these things.

I guess it's still used to heat food.

It was first used for electromagnetic waves.

He was first used for electromagnetic induction

The purpose of microwave ovens has not changed much.

At first, it was used to heat food, and later it was used to bake bread for cooking.

Answer]: B Problem Solving Guidance: Physics General Knowledge Questions. Microwaves cause molecular resonance in the food in the microwave oven through the vibration of the waves. The vigorous motion of the molecules causes an increase in the energy inside the object, which is manifested as an increase in temperature. So the answer is b.

Summary. Microwave oven When microwaves are radiated to food, the food always contains a certain amount of water, and water is composed of polar molecules (the positive and negative charge centers of molecules, which do not coincide even when the external electric field is not present), and the orientation of this polar molecule will vary with the microwave field.

What does a microwave make use of? And what thermal effect does the halogen oven use?

The heating principle of the halogen oven is to use light waves instead of microwaves, and light wave heating has more different characteristics than microwaves. The halogen oven actually uses a lamp to generate heat, and then uses a high-efficiency reflector disc to concentrate the heat energy emitted on a glass panel that can withstand high temperatures. Through this glass panel, heat is transferred at high speed to the heated container that needs to be heated with a full load of food.

The heat generated by halogen ovens is actually a type of halogen light that relies on far-infrared halogen lamps to generate heat, so halogen ovens can be called far-infrared halogen furnaces. After the heat is generated through the halogen lamp, the heat is concentrated by high-efficiency reflection, which is concentrated like a convex lens, and finally the heat is transferred through the high-temperature glass-ceramic panel. The user can then place the food on this panel and heat it.

Summary. Microwave ovens are mainly used to defrost food, and microwave ovens are mainly used to cook food.

The microwave oven can make cakes, grilled chicken wings, and various dishes, such as braised pork, plum cabbage button pork, fish-flavored shredded pork, and so on. In addition, the microwave oven can also make soups such as seafood soup, hot and sour soup, corn soup, tomato beef soup, and so on. There are also microwave ovens, which are mainly used for sterilization and disinfection.

The cooking temperature of the microwave oven on high heat is very high, and if you put the food in it, all the bacteria contained in it will be killed. If you're looking for healthy food, you can also try using a microwave oven to sterilize your food.

A microwave oven is a common household appliance, and what are its uses besides heating food?

The main uses of the microwave oven are to defrost food, and the main purpose of the microwave oven is to cook delicious food, the microwave oven can make cakes, grilled chicken wings, and can also make various dishes, such as braised pork, plum cabbage button meat, fish-flavored shredded pork and so on. In addition, the microwave oven can also make soups such as seafood soup, hot and sour soup, corn soup, tomato beef soup, and so on. There are also microwave ovens, the main uses are sterilization and disinfection, the cooking temperature of the microwave oven is very high, and the bacteria contained in the food will be completely killed.

If you're looking for healthy food, you can also try using a microwave oven to sterilize your food.
