When an electric kettle containing cold water is switched on, the water in it starts boiling after a few minutes. what best describes the heat energy of the boiling water? it is the transformed electrical energy. overall energy is lowered due to this heat. gravitational energy changes to form this heat energy. it causes an increase in the overall energy of the system.

It is the transformed electrical energy.

Explanation:

When there is an electric kettle introduced into cold water, it will make the water temperature to rise up this is because the electric kettle is basically a resistance that is heating up because the electric energy doesnot have a place to go, so its basically a piece of metal that is heating up because of the electricity that is ciculating through it, so the heat energy is the electrical energy transformed.
