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.
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 much energy is used to boil a kettle once?
Boiling a kettle once typically uses around 2000 to 2500 watts of energy for a few minutes, depending on the size and efficiency of the kettle. This can roughly translate to 0.04 to 0.06 kilowatt-hours (kWh) of electricity consumed per boil.
Why does it take longer for a full kettle of water to boil than a half full kettle?
A full kettle of water takes longer to boil than a half full kettle because more water requires more energy to heat up to the boiling point. The greater volume of water in a full kettle absorbs more heat energy before it reaches the boiling point, leading to a longer heating time.
How do you increase a kettle's efficiency?
To increase a kettle's efficiency, you can use a kettle that is the right size for your needs, regularly descale it to remove mineral buildup, and match the heat source to the kettle material. Additionally, keeping the kettle lid on while heating water and using an insulated kettle can help retain heat and improve efficiency.

Why would a plastic kettle stay hotter than a metel kettle?
How long something stays hot depends on its heat capacity. Heat capacity is a measure of the amount of energy required to change the temperature of an object.Water has a relatively large heat capacity per gram whereas metals have a low heat capacity. This means that water retains it heat but metals heat and cool quickly. We can take a metal tray from an oven and put it to cool, we can touch the tray soon afterwards but the roast that we put on the serving platter stays hot for a lot longer.The plastic in the kettle will cool depending on its heat capacity. Metal cools quickly due to its low heat capacity.
