If you are heating water on stove why does it take a while for the water to boil

Answers

Answer:

Common sense should tell you the answer!

More water = more mass = more time, basic school physics.

Explanation:

If heat energy is supplied at a roughly constant rate by the heat source then the time taken to supply the total energy needed to boil is calculated from E = Pt. The energy required simply depends on the mass of water. E = m x SHC x temp change. so t = m x SHC x dT/P.

Answer:

Because the pan/pot has to get to the right temp first.

Explanation:

The water boils at a lower temperature. So the pan will boil faster as it doesn't have to reach 100 degrees C to boil the water.
