You have two identical open pots, each with the same amount of water. Pot A is on a low heat setting, and Pot B is on a high heat setting. Which pot will reach its boiling point faster?
A) Pot A will boil faster because low heat is gentler.B) Pot B will boil faster because high heat adds energy more quickly.
C) Both pots will boil at the same time because they have the same amount of water.
