How does boiling happen?

Answer 1

Boiling destroys the vast majority of bacteria that is often found on the outer parts of food. In some cases the heating action helps make the food more digestible, which allows the body to take advantage of nutrients it might not be able to break down on its own.

Answer 2

We see boiling as a phase change of matter. The matter attains so much thermal energy that its vapoure pressure rises to equal that of atmospheric pressure. The atoms or molecules that are boiling are "escaping" into the surrounding air because the pressure of the heated liquid allows them to "push off" out of the liquid and into the surrounding air.

Answer 3

By using the steam.

Foods may be cooked using hot water by:

Boiling: e.g. pasta, potatoes, rice, etc. Boiling means the water temperature remains hot enough for large bubbles to constantly form in the water.

The food is put into boiling water and left to boil, usually uncovered, until cooked. Frequently, the food is stirred as it cooks to ensure even cooking or to prevent it sticking to the pot.

In some cases, foods (such as eggs for hard boiling, or potatoes for blanching) are put into cold water and then brought to the boil.

Simmering: e.g. vegetables, rice, some meats, etc. Simmering means the water is lightly bubbling but not boiling. A gentle simmer means the water is just moving, with the occasional bubble rising to the surface.

The food is either put into cold water and brought to simmering point or put into already simmering water, and simmered until cooked; as with boiling the food is usually stirred during cooking. The pot may be covered or uncovered, depending on the food.

Steaming: e.g. vegetables, rice, some puddings, etc. The food is put into a very small amount of simmering water until cooked, or the food is put into a steamer - which can be just a metal bowl, or a steamer basket (usually available from the supermarket) - set into the pan above, but not touching, the simmering water. In this case the water can be set at a fairly high simmer to create more steam.

*Some foods, such as instant noodles, are cooked by placing in a container and pouring boiling water over them from a kettle or pan. They are then left to allow the heat to cook them as per the packet instructions.

Answer 4

Heat. Heat is pretty much it. For an example, if you were cookingspaghetti, the noodles will absorb the water and make themsofter, then heat will break the water into a steam and make thenoodles soft and edible over time.

Answer 5

you put enough water in a pan to cover what ever it s that you will be cooking and you turn the flame on low to medium heat till it starts to bubble/boil like mad. that shuld be 212 degrees Fahrenheit and 100 degrees celcius. boil whatever you are cooking fro a little while and then test it by poking it with a fork or tasting it to make sure you have the right texture and has been cooked right. pour your water out threw a strainer and then quickly pour cold water over it to wask away gluten and to make it so it wont turn to paste quickly or stick together.

Answer 6

The boiling water heats up the potato from the heat in the water.

Answer 7

You should heat water up to 100 Celsius degrees and the water will start to seethe.

Answer 8

Boiling is one way to cook food. POther ways of cooking food are baking, grilling, broiling, sauteing, frying, steaming, etc. To cook food by boiling is to immersed the food in boiling water.
