this happens because the high pressure wants to go to low pressure
a negro kettle.
If temp. remains constant, the volume of certain amount of gas is inversely proportional to its pressure.
the kettle boils and then the energy comes out as steam
The amount of electricity it would take to boil a kettle would be phenomenal, regardless of whether the kettle is made from metal or plastic. I suggest instead you try boiling the water inside the kettle first.
If you imagine the world as a kettle of boiling water, standing on a lit gas ring. While the steam escapes through the spout, all is well. But if the spout and lid was to become blocked, the steam would create a growing pressure inside the kettle. Eventually, the kettle would burst and the pressure is suddenly released. A bursting kettle is like an erupting volcano, releasing some of the pressure that had built up below the mantle.
steam comes out to release the energy of the kettle because of the heat that it's producing
Air pressure is higher at sea-level, so a kettle will boil quickly. Air pressure lessens the higher one climbs, so a kettle will take a long time to boil on the top of Mount Everest.
As you get deeper the pressure of water increases.
The mist escapes the kettle because of the high pressure. Outside, the temperature and pressure are much lower (room temperature and 1 ATM pressure), so water condenses again since it's liquid in such conditions.
it doesn't :)
When a tea kettle whistles, it is because the liquid inside turns to steam and is forced by pressure through the small opening in the kettle lid. This phase change is a physical change, not a chemical one.
assuming both containers are at the same elevation, there in fact can be a difference. Boiling point is defined as "the temperature at which the vapor pressure of the liquid equals the environmental pressure surrounding the liquid" If the kettle were sealed or at least mostly sealed, as steam began to spew from the kettle spout, if it in fact filled the inside with enough pressure (more steam stacks up than is able to escape the kettle) the boiling point would in fact rise slightly. This idea is similar to why a person who quickly opens a pressure cooker will deal with a vicious explosion as the pressure inside the pot equalizes with the pressure outside of it, therefore water and steam essentially explode outwards.
That would be the boiling point of water, or somewhere below if the kettle is faulty. The boiling point of water is 100 degrees Celsius.That would be 212 degrees Fahrenheit.
As the depth increases the pressure goes on increasing. Pressure is same at the same level. ..........................................Gho$t
Boiler have minimum pressure 28 bar as per. Indian boiler act.so p c xan not call a boiler
total pressure = sum of all partial pressures.
