How does heat stay in a metal kettle?
Once the heat has been turned off the kettle, it will begin to lose heat. The rate of heat loss depends on the thickness of the kettle's walls, the amount of boiling water that was in the kettle before the heat was turned off, and the temperature of the room the kettle is stood in. When tea is traditionally brewed in teapots, a woolly knitted cover (known as a cosy - in the UK) was placed over the teapot to slow down the rate of heat loss.
Which has greater heat energy water tank of electric kettle?
the tank must have a graeter amount of energy because it has to heat up more water there for it requirs more energy to do so
What contains the most heat energy a kettle or a tank?
a negro kettle.
Examples of heating effect of electric current?
-kettle -electric heater that's all i have! :)) When a current passes through a wire, the wire heats up. This is caused by the conversion of electrical energy into heat energy. /the heat produced depends on the resistance of the wire.
What is the wasted energy for a kettle?
By the fact that the kettle is hot. The heat energy is also warming the metal of the kettle. By the fact that the water boils to steam,; loss of water to steam. The energy should only heat the water to boiling point, and not heat the kettle nor allow the water to boil off.
Which part 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.

How does an electric kettle get energy?
The kettle has to be plugged in to an energy supply before it can heat up.
What is the function electric kettle?
To heat up water *facepalm*
What is happening inside the kettle with water?
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.

Why does a kettle have 800 watts?
Assuming you got that number off an electric kettle it is because that is how much power is needed to heat the water. The number of watts actually measure how much energy the kettle is designed to use. Water is very hard to heat compared to other liquids(or to cool). So it takes a lot of watts to get the kettle to heat the water.
Does a plastic kettle handle prevent or helps heat flow?
Plastic is a good insulator of heat, meaning heat can't flow through it very well. So a plastic handle on a kettle doesn't conduct heat through it and this means you don't get burnt when handling it.
Why was the kettle invented?
The kettle was invented to boil water, first ones were placed directly onto a stove top (much like a pot); later electric ones use an element to heat the water
When an electric kettle is switched on it will take a few minutes to heat the water how does the element at the bottom of the kettle heat all of the water?
As water at the bottom is heated, it rises and cold water replaces it. That's heated and the cycle continues until all the water is at the same temperature.
Is the energy source for a kettle electrical or heat?
the stove is used if it is a heat kettle otherwise it is electrical based
Which has greater heat energy water tank of electric kettle?
the tank must have a graeter amount of energy because it has to heat up more water there for it requirs more energy to do so
