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.

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.
What contains the most heat energy a kettle or a tank?
a negro kettle.
What type of energy does a kettle use and what types of energy does it get converted to?
A kettle uses electrical energy and converts it into heat energy.
Give a reason why the kettle loses less heat than the saucepan by the process of conduction?
because the kettle is made of plastic
Does juice temperature increase with increasing convective heat transfer coefficient at any constant kettle surface temperature?
Yes, the juice temperature increases with an increasing convective heat transfer coefficient at any constant kettle surface temperature. The convective heat transfer coefficient represents the efficiency of heat transfer from the kettle to the juice. As the convective heat transfer coefficient rises, more heat is transferred from the kettle surface to the juice per unit of time. This increased efficiency results in a faster temperature rise in the juice. Therefore, a higher convective heat transfer coefficient enhances the overall heating process, leading to a greater temperature increase in the juice even when the kettle surface temperature remains constant.
Do a kettle heat faster with metal plate with gaps?
No

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.
Why are kettles made out of iron?
Many kettles are made of metal, and a "polished" or "finished" metal kettle will often appear silver because that is the color of the metal used to make it.
