First, a 'Bi-metallic Strip' consisting of two different metals, having different 'Coefficients of Expansion', fused together in a two-layer strip which is connected electrically to the kettle element power supply.
It is placed in a chamber, generally in the kettle handle, where steam from the top of the kettle can come into contact with the chamber holding the metal strip. (Not with the strip itself).
When at room temp., the electrical contacts are closed allowing current to flow to the Element when power is switched on.
When the kettle boils, steam is passed around the chamber that contains the strip, causing it to heat up.
The metal having the higher 'C of E' of the two making up the bi-metal strip, will expand more than the other, causing the strip to bend and open the contacts, thus shutting off the power.

In an electric kettle water becomes hot by?
In an electric kettle, water becomes hot by using a heating element that heats up when the kettle is turned on. The heating element transfers heat to the water, raising its temperature until it reaches boiling point.
What is happening inside the kettle with water?
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.
How does a Crofton Electric Water Kettle work?
There is a heating element in the kettle. As the water boils, the inner temperature of the kettle rises. Once the boiling temperature is reached, a small thermostat is triggered which turns the kettle off, so as to not boil continually. This thermostat works optimally with the lid on the kettle fully closed, if the lid is not fully closed, it does not switch the kettle off as quickly.
When does gas changes to liquid?
When it reaches it's boiling point.
The body loses heat by the evaporation of sweat how is a tea kettle boiling on the stove similar to the evaporation of sweat from the body Thx?
Both the evaporation of sweat from the body and the boiling of water in a tea kettle involve the transition of a liquid to a gas, which requires energy. When sweat evaporates from the skin, it absorbs heat from the body, helping to cool it down, similar to how the water in a kettle absorbs heat from the stove until it reaches its boiling point. In both cases, the process of evaporation removes heat from the surrounding environment, whether it's the body or the kettle, resulting in a cooling effect.
In an electric kettle water becomes hot by?
In an electric kettle, water becomes hot by using a heating element that heats up when the kettle is turned on. The heating element transfers heat to the water, raising its temperature until it reaches boiling point.
What energy is used when boiling a kettle?
The energy used when boiling a kettle typically comes from electricity in the form of heat. The heat is transferred from the heating element in the kettle to the water, raising its temperature until it reaches the boiling point.
What heat occurs inside the kettle?
When a kettle is turned on, an electric current passes through the heating element, causing it to heat up. The heat generated by the heating element is then transferred to the water in the kettle through conduction, raising the temperature of the water until it reaches boiling point.
What is happening inside the kettle with water?
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 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 process for a kettle?
A kettle is a simple appliance that heats water using electricity or gas. Water is poured into the kettle, the heating element is turned on, and the water is heated until it reaches the desired temperature. The kettle will automatically shut off once the water reaches boiling point or the desired temperature.
Does a kettle use or produce heat?
A kettle uses heat to boil water. The heat is typically applied through a heating element in the kettle that warms up the water inside until it reaches boiling point.
How does a Crofton Electric Water Kettle work?

How does a kettle turn off?
An electric kettle basically is a kitchenware piece, usually made of durable plastic or stainless steel and are powered by electricity. This allows someone to quickly heat water for hot drinks like tea or coffee. Once the water inside reaches the boiling point (212 degrees Fahrenheit), the kettle automatically deactivates itself to avoid the contents from boiling away and damaging the heating element. The older manual kettles are heated over a flame or electrical element but do no have any wiring. The boiling point is indicated by a whistle activated by the escaping steam, at which point the kettle should be removed from the heat source.
What is the boiling point of a kettle?
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.
How a normal kettle works?
A normal kettle is a semi-closed metal container (with lid and spout) of water. When placed on a flame, the water inside the kettle heats up until it reaches boiling point. It is then ready to be taken off the flame and the boiling water poured into a teapot, or some other beverage, etc.
Is a kettle boiling a chemical reaction?
When a kettle is boiling you are able to see the chemical reaction, from the stem leaving the kettle.
