Question

explain why the heating element of an electric kettle is at the bottom?

Answer 1

Hey buddy,

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.
