< BR> Some people used to pour the water into a cup
Microwave ovens
In heating, then for tea. However, when put into a tea cup, glass of water will immediately emerge a lot of bubbles, even water boiling up, and very intense, a horrible.
This is the cup of water in the overheated state of some of the reasons, that is, this part of the water temperature actually higher than the boiling point. Glass of water boiling in a microwave oven is not reason, it is because the lack of formation of water bubbles into a nuclear center (condensation nuclei).
If we would not use the kettle boil this phenomenon, because there are rough inner surface of the bottle, but also stir the hot water rising from the Hu Di, which can make the normal boiling water. The microwave oven work, the water circulation does not occur. In the absence of condensation nuclei, the water will not produce bubbles, and sometimes can not see the rolling boiling, it can not know whether the water is boiling.
A long time if the heating, water may have been burned more and more heat, even more than the boiling point, when the water is too hot. When you filled with hot water in the microwave container on the table, just slightly crashing, the water inside the container will be disturbed, the water flow will be triggered to play the role of a condensation nuclei, leading to the water suddenly boiling, spills, or even cause burns. To prevent this to happen, any liquid heated in a microwave, heated it in the furnace must stand for at least a minute, and then open it to take action.
Microwave cooking with less salt
Experiments confirmed that the higher salt content in foods, food surfaces, the easier the formation of induced current circulation, the current can microwave energy deep into the center of the food in no position to fully heat the food was consumed before. Thus, microwave cooking, adding too much salt, not only make more difficult to cooked food, but also the center of a bacterial cause of food survival. Therefore, the need for microwave cooking of food or less salt is good, the best food to be cooked and then salt.
