It is a secret
When you put the switch on, the electricity goes thought the wires heating the melt prongs, which heats the kettle and the water. When you put the switch on, the electricity goes thought the wires heating the melt prongs, which heats the kettle and the water.
It's basically the same as the glow wires in a toaster, or the filament in an incandescent light bulb. When a current is passed through the element, the resistance makes the element heat up.Another AnswerWhen an electric current passes through the heating element, it does work on the heating element, water, and the kettle itself. This causes the internal energy of the element, water, and kettle to rise, and this is accompanied by an increase in temperature. When the temperature exceeds that of the surroundings, some energy is lost to the surroundings through heat transfer. The equation that describes this is:W - Q = [m c (T2 - T1)]water +[m c (T2 - T1)]kettleWhere:W = work done (joules)Q = heat transfer (joules)m = mass (kilograms)c = specific heat capacity (joules per kilogram kelvin)T2 = final temperature (kelvin)T1 = initial temperature (kelvin)
Water boils into steam at 100C or 212F at sea-level pressure.
An electric kettle is a convenient and efficient appliance used for boiling water quickly. It's perfect for individuals or small households who need to prepare hot water for making tea, coffee, instant noodles, or other hot beverages and food items. If you are looking for brand electric kettle KENSTAR as well-regarded electric kettle known for their quality, performance, and safety features.
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.
no. it means that the kettle can be unplugged from the electricity source. the heating source is in touch with water, as it is located inside the kettle :)
a kettle is made out of metal

Yes, the juice temperature increases with an increasing convective heat transfer coefficient at any constant kettle surface temperature. The convective heat transfer coefficient represents the efficiency of heat transfer from the kettle to the juice. As the convective heat transfer coefficient rises, more heat is transferred from the kettle surface to the juice per unit of time. This increased efficiency results in a faster temperature rise in the juice. Therefore, a higher convective heat transfer coefficient enhances the overall heating process, leading to a greater temperature increase in the juice even when the kettle surface temperature remains constant.

the kettle is made from iron. Matter passes through and that's why the water is the same temperature as the bottom of the kettle.

Kettle?haha :P
A kettle is used for boiling water usually used for making a cup of coffee or tea.
