Question

Will the water be heated efficiently, if the heating element in the electric kettle is at the top of the kettle?
Justify your answer.

Answer 1

Answer:

If you placed the heating element at the top and the kettle isn't full, the water wouldn't get heated because the element isn't there so you would still have cold or at most lukewarm water.When it's at the bottom, hot water weighs less than cold water so it rises to the top, thus heating all the way through.

Answer 2

In other words, the element gets hot. Since it's in direct contact with cold water, the heat passes to the water by conduction and rapidly warms it up too. Photo: Top: The heating element inside the base of the electric kettle shown in our upper photo
