When the water boils, the steam collects in the top part of the kettle. Then, the air above the water is saturated with steam. The boiling stops momentarily and the steam is then pushed out. As the steam is pushed out, it produces a whistling noise. ----
Early in the boiling process, the water has a very unequal distribution of heat. This causes small pockets of water (where the temperature is highest) to vaporize and produce small steam bubbles, and it's those small bubbles (as they release from the bottom of the pan, force their way up through the cooler water, and burst at the top) that set up tiny explosive vibrations that are picked up and amplified by the metal of the pot. As the water gets closer to boiling, though, the distribution of heat in the liquid begins to even out, and instead of forming small localized vapor bubbles, the hotter water at the bottom tends to rise as a whole while the cooler water at the top falls as a whole, producing a kind of rolling cell; water vapor is produced and released almost exclusively at the top of the liquid, so there are far fewer bubbles to explode and set up vibrations, hence less sound. ----
The boiling point of water depends on air pressure. A plateau about one and a half kilometers high will have a lower atmospheric pressure than at sea level. Thus, water will boil at a lower temperature at that high plateau. Now, that silence is due to almost reaching the required temperature to overcome the pressure and thus continue. It's like an energy absorption. The whistling: Many kettles are designed to make a whistling noise at boiling point so we can know when the water has boiled. It does not whistle before this because the water vapor coming out is not yet enough to make a noise.
What else can I help you with?
Does steam come out of a kettle?
Yes, when water boils inside a kettle, steam is formed and it comes out of the spout.
What would happen if a kettle is filled to the max while the kettle is boiling?
If a kettle is overfilled while boiling, the boiling water can overflow, causing a mess and potentially a safety hazard. It is best to ensure there is enough space in a kettle to accommodate the water expanding as it boils.
When a kettle boils what are the energy transfers?
When a kettle boils, energy is transferred from the electric heating element to the water in the form of heat. The heat energy causes the water to increase in temperature until it reaches its boiling point, at which point some of the heat energy is also used to convert the water into steam.
What is the energy out of a whistling tea kettle?
The energy output of a whistling tea kettle is in the form of sound and heat. As the water boils and creates steam, the kettle whistles to signal that the water is ready. The heat energy is transferred to the water to raise its temperature to boiling point.
How does a kettle relate to pressure?
A kettle uses pressure to heat water. As the water boils and turns into steam, the pressure inside the kettle increases, causing the steam to escape through the spout. This pressure buildup is what allows the water to reach its boiling point temperature faster.
Does steam come out of a kettle?
Yes, when water boils inside a kettle, steam is formed and it comes out of the spout.
When the kettle boils how hot is the steam in celsius?
It will be the boiling point of water: 100oC
What place would have the temperature of 100 degrees celsius?
The inside of a kettle as water boils.
Of a kettle boils and water turns to steam is it a chemical or physical reaction?
Its a chemical reaction :]
What would happen if a kettle is filled to the max while the kettle is boiling?
If a kettle is overfilled while boiling, the boiling water can overflow, causing a mess and potentially a safety hazard. It is best to ensure there is enough space in a kettle to accommodate the water expanding as it boils.
What is the container called that boils water?
The container that you can boil water in is called a beaker.
When a kettle boils what are the energy transfers?
When a kettle boils, energy is transferred from the electric heating element to the water in the form of heat. The heat energy causes the water to increase in temperature until it reaches its boiling point, at which point some of the heat energy is also used to convert the water into steam.
What happens when the watel boils in the kettle?
When water boils in a kettle, it reaches its boiling point and turns into steam. This is caused by the heat energy applied to the water that overcomes the intermolecular forces holding the water molecules together. The steam rises, creating bubbles and a hissing sound, and the water changes from a liquid to a gas state.
What happens when a tea kettle whistles?
When a tea kettles water boils, steam exits the hole in the sound of a loud whistle.
What is the energy out of a whistling tea kettle?
The energy output of a whistling tea kettle is in the form of sound and heat. As the water boils and creates steam, the kettle whistles to signal that the water is ready. The heat energy is transferred to the water to raise its temperature to boiling point.
Can you bath your stardox alien?
yes but do it is boiling water and but t in the kettle while it boils then after put it in the fridge
