Question

Why does hot water boil faster then cold water

In: Physics

Answer 1

It’s got more energy in it. You have to raise the thermal energy of hot water less than cold water to boil it because there is already more energy in it. Imagine it like filling two bags of popcorn at the same rate although one is already half full, the half full one will be filled more rapidly.
