How is energy conserved when a pan of water on an electrical stove comes to a boil​
Bumek [7]

Answer:

Here’s what I find.

Explanation:

The electrical coil on the stove provides heat energy (q).

This energy is used to

  • heat the pan (q1)
  • heat the water (q2)
  • convert the water to steam (q3)

and some of the energy is wasted by radiation into the surroundings (q4)

The energy conservation would be

q = q1 + q2 + q3 + q4
