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)]kettle
Where:
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)

How water heat in a kettle?
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.
Which would be the best name for a function that takes the time spent heating a kettle and returns the temperature of the kettle?
Time(temperature)
Do a kettle heat faster with metal plate with gaps?
No
Which parts of the electric kettle are made of good insulators of heat?
The outer part as the part you hold the kettle from to prevent injures.
What is an electric kettle?
A kettle is something where you can make coffee or tea. You can also use them to heat up baby bottles. To heat up a baby bottle, press the button wait for the kettle to boil then you pour a bit of the hot water into a big cup, put the bottle in it and wait a couple of minutes. After a few minutes check to see if it's warm enough for a baby to drink.It is very useful for cleaning hard water by boiling.
How does a kettle produce heat?
A kettle produces heat by converting electrical energy into heat energy through a heating element, usually made of metal. When the kettle is turned on, the heating element heats up, warming the water inside the kettle through conduction.
What material is used to make the kettle heating element?
Most kettle heating elements are made of a metallic material, such as stainless steel or nickel-chromium alloy. These materials are chosen for their heat resistance, durability, and ability to efficiently transfer heat to the water.
Why the heating element of an electric kettle is not placed in the middle of the kettle?
Placing the heating element at the bottom of the kettle allows heat to be directly transferred to the water, resulting in quicker and more uniform heating. If the heating element were in the middle, the water at the top of the kettle would take longer to heat up and there could be hot spots in the water.
How does conduction in a kettle work?
In a kettle, conduction occurs when heat energy is transferred from the heating element to the water through direct contact. The material of the kettle, usually metal, allows the heat to conduct through it and into the water, causing the water to heat up. The heating element inside the kettle is responsible for providing the initial heat energy that starts the conduction process.
How does a kettle become hot?
A kettle becomes hot by converting electrical energy into heat through a heating element inside the kettle. When the kettle is plugged in and turned on, the electrical current flows through the heating element, which generates heat that warms the water inside the kettle.
Does cordless kettle mean that the heating element is not in cotact with water?
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 :)
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.
How does an electric kettle heat up water?
An electric kettle heats up water by using an electric heating element located at the bottom of the kettle. When the kettle is plugged in and turned on, the electric current passes through the heating element, generating heat. This heat transfers to the water, causing it to heat up and eventually boil.
What energy transformation in kettle?
In a kettle, electrical energy is transformed into thermal energy through the process of resistive heating. The heating element inside the kettle uses the electrical energy to generate heat, which raises the temperature of the water inside the kettle.
What is an electric element?
An electric element is a metal part inside a kettle that makes the wate get hot
Why is the heating element in an electric kettle positioned very close to the bottom of the kettle?
The heating element is positioned close to the bottom of the electric kettle to ensure efficient transfer of heat to the water. Placing it near the bottom helps heat the water evenly and quickly, leading to faster boiling times. Additionally, it helps prevent damage to the kettle by keeping the element submerged in water at all times.
Does the wire in the electrical cord of an electric kettle have a higher or lower resistance than the heating element inside the kettle?
The wire in the cord has much lower resistance than the heating element. The heating element is a resistive or resistance heating element. Resistance in the quality of a substance or material that causes it to limit current flow, and it get heated up in the process. The heating element has all but the smallest fraction of the resistance in the circuit, so the heat, that thermal energy that get the water hot, is generated by the resistance of the heating element.
