The boiling point of water depends on the atmospheric pressure which changes according to elevation. A lower boiling point means that food cooks at a lower temperature despite the fact that the water is boiling.

What temp to boil water. Water heating time calculator. Boiling point of water is considered to be 100 â c or 212 â f. If you re warming water in a pot this means it will have either tiny bubbles forming in the bottom of the pot or tiny bubbles about 3 mm rapidly rising to the surface of the pot.
Another factor that can affect the boiling temperature of water is the material that the vessel it s being boiled in is made of. Boiling time of water can be calculated with the volume energy efficiency start and end temperature. Most green teas are best when brewed well below boiling temp 212 f at somewhere between 150 f and 180 f.
How to calculate the boiling point of water. Experiments have shown that at the same pressure water will boil at different temperatures in metal and glass vessels. Boiling or heating is the process of rapid vaporization of the liquid to reach its boiling point.
To do so you will need a heat source such as a cooker or camping stove and a vessel to hold the water. Boiling purifies water through heat. Changes in atmospheric pressure will alter the temperature at which water boils.
What is the boiling point of water. A medlo setting will boil water in a 1 5q saucepan easily enough but a 14l stocker of cold water might take all day reach a boil at that setting. It is important to recognize just how much the temperature of boiling water is reduced as the altitude increases.
Advantages of boiling water for drinking. The heat supplied by the source raises the temperature of the water to about 212 f 100 c. My 10 imperial gallon stocker barely reaches boiling even on high and it takes a loooooooooooooong time.
Water boils at a lower temperature as you gain altitude e g going higher on a mountain and boils at a higher temperature if you increase atmospheric pressure coming back down to sea level or going below it. To use this calculator you will need your current pressure and elevation. The key is managing the temperature of the water so it stays hot enough to cook the food thoroughly and evenly and long enough to kill any food borne pathogens that may be in the bag along with.
Why boiling purifies water. This temperature is too high to support life. Water boils at 212 f at sea level but only at sea level.
Boiling water is the most effective method of purifying it.
