The steam from a kettle will hit the cold window surface and lose heat rapidly, causing it to condense back into water droplets. This is because the cold window cools down the steam quickly, which is why you can see the steam forming water droplets on the window.
Inside the kettle, the water is being heated by an electric element or flame. As the water absorbs heat, its temperature rises and eventually reaches the boiling point, causing it to turn into steam. The pressure from the steam builds up inside the kettle until it forces the steam out through the spout, producing the whistling sound characteristic of a boiling kettle.
Typically, only one gas, such as natural gas or propane, is used to heat a kettle for boiling water or cooking. Other gases, such as steam or air, may be produced during the boiling process, but they are not directly input into the kettle.
The formation of steam from boiling water in a kettle is a physical change. It involves a phase change from liquid to gas without altering the chemical composition of the water molecules.
The process of a kettle of water boiling to form steam is reversible, as it can be reversed by cooling the steam back into water. This transformation involves a change in state from liquid water to gaseous steam and is driven by the input of heat energy.
If you look carefully at a boiling kettle, water vapour is the white vapour you can see. Steam is actually the invisible short section between the spout of the kettle and the start of the water vapour.
Actually, the steam part is not actually steam, but water vapour. If you look closely at a boiling kettle, there is a clear space between the spout and the actual (steam). That clear space is the steam, which is invisible. What appears afterwards is water vapour.
The kettle was clearly boiling as they could see the steam rising from it.
When a kettle whistles it is because steam from the boiling water inside is escaping through a whistle on the kettle.
It will be the boiling point of water: 100oC
The sound of a kettle boiling is commonly referred to as a whistle or a hiss. It is caused by the steam escaping through the spout or pressure release valve of the kettle.
The temperature of steam from a kettle is typically around 100 degrees Celsius (212 degrees Fahrenheit) at sea level, which is the boiling point of water.
When boiling water, the steam produced escapes through a small hole in the kettle's spout. The vibrating steam creates the whistling sound we hear, signaling that the water has reached the boiling point.
Inside the kettle, the water is being heated by an electric element or flame. As the water absorbs heat, its temperature rises and eventually reaches the boiling point, causing it to turn into steam. The pressure from the steam builds up inside the kettle until it forces the steam out through the spout, producing the whistling sound characteristic of a boiling kettle.
When they say boiling water they mean some water is turning to steam but not all off the water has to be over 100 degrees for some to be boiling.
steam from your kettle that turns to water on your window!!
Steam comes out of the kettle's spout when the water inside reaches its boiling point and turns into vapor. This is a natural result of the heat causing the water to evaporate and escape through the spout, creating the visible steam.
Typically, only one gas, such as natural gas or propane, is used to heat a kettle for boiling water or cooking. Other gases, such as steam or air, may be produced during the boiling process, but they are not directly input into the kettle.
