If you put heat under the kettle, the water eventually boils. If it's an electric kettle, you plug it in and switch on the electricity.
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.
If all you do is watch it, it will never boil.A kettle with no water in it will never boil.The kettle actually won't boil, just the water that is in it.The kettle may seem as if it never boils while you are watching it because the process is about as exciting as watching paint dry.
When a kettle boils, some of the water inside goes from the liquid state to the gaseous state and rises because it's hot. What you see on your cupboard is called condensation which happens when a gas is cooled, such as steam (gaseous water), and goes back to the liquid state, hence why you have liquid water up there.
What causes the water to evaporate? For me, heat causes the water to evaporate, like the boiling water in the kettle. When it boils you can see moist on the top of the kettle. So the heat causes the water to evaporate. =D
No
When a kettle whistles it is because steam from the boiling water inside is escaping through a whistle on the kettle.
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 :)
Hi there when the kettle is boiled the water inside is heated up to boiling point.This is because the coil inside the kettle gets heated by electricity very rapidly and transfers the heat to the water making it boil. The coil some times get a build up of natural chemicals on it such as limescale and therefore has to be cleaned . Now a days we have filter kettles which get rid of the limescale as water is added to the kettle.
The inside of a kettle as water boils.
Lime scale will eventually coat the inside of the kettle. Unless this layer of lime scale is regularly removed, the efficiency of the kettle to boil water fast is impaired.
All I ever do is every now and then rinse out with some vinegar and water. This is just to remove hard water buildup though. The heat from the kettle will kill all germs.

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.
The amount of electricity it would take to boil a kettle would be phenomenal, regardless of whether the kettle is made from metal or plastic. I suggest instead you try boiling the water inside the kettle first.

If the water in the cup came from the kettle, it will be cooler than the water that remains in the kettle. Since the water in the cup is more exposed to the air than the kettle it will lose heat to evaporation more quickly than the water in the kettle will. The cup will also conduct heat way from the water until the water and the cup are the same temperature, whereas the kettle is already as hot as the water it contains.
It depends on the size of the kettle.
