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.

How does an electric kettle work to heat water efficiently and quickly?
An electric kettle works by using a heating element to quickly heat water. When the kettle is turned on, electricity flows through the heating element, which generates heat. The heat is transferred to the water, causing it to heat up rapidly. The design of the kettle allows for efficient heat transfer, resulting in fast boiling times.
Which has greater heat energy water tank of electric kettle?
The water tank of an electric kettle typically has more heat energy than a regular cup of water at the same temperature. This is because the electric kettle is designed to heat a larger volume of water to a higher temperature, thus storing more heat energy.
What is the principal energy transformation occurring in an electric kettle?
The principal energy transformation in an electric kettle is electrical energy being converted into heat energy through the process of electrical resistance in the heating element. This allows the water in the kettle to heat up and eventually boil, generating steam.
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.
Why the handle and lid of the electric kettle are made up of good insulators of heat?
The handle and lid of an electric kettle are made up of good insulators of heat to prevent burns or heat transfer when touching or opening the kettle during or after boiling. Using insulating materials helps keep the exterior of the kettle cool to touch while maintaining a safe temperature inside for boiling water. This design ensures user safety and convenience when handling the kettle.
What is the function electric kettle?
To heat up water *facepalm*
Does water decompose in an electric kettle?
Water does not decompose in an electric kettle. The water will heat up and either evaporate into steam or remain as liquid water.

How does an electric kettle get energy?
The kettle has to be plugged in to an energy supply before it can heat up.
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 the principal energy transformation occurring in an electric kettle?
The principal energy transformation in an electric kettle is electrical energy being converted into heat energy through the process of electrical resistance in the heating element. This allows the water in the kettle to heat up and eventually boil, generating steam.
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.

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.
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.
Why the handle and lid of the electric kettle are made up of good insulators of heat?
The handle and lid of an electric kettle are made up of good insulators of heat to prevent burns or heat transfer when touching or opening the kettle during or after boiling. Using insulating materials helps keep the exterior of the kettle cool to touch while maintaining a safe temperature inside for boiling water. This design ensures user safety and convenience when handling the kettle.
How does the cover of an electric kettle prevent heat loss?
The cover of an electric kettle prevents heat loss by trapping the heat inside, creating a seal that prevents air circulation. This helps to maintain the temperature of the water inside the kettle and speeds up the boiling process by concentrating the heat. Additionally, the cover usually contains insulation materials that further reduce heat loss.
