Objective

  • To determine whether cold water boils faster than warm water
  • To understand the implications of water temperature.

  • Two pots
  • Warm water
  • Cold water

Introduction

The mpemba effect can cause hot water to freeze faster than cold water.This has led to a popular kitchen myth: that the opposite is also true.Namely, that cold water boils faster than hot water.How true is this?

Research Questions
  • Does cold water boil faster than hot water?
Terms, Concepts and Questions to Start Background Research
  • What is the mpemba effect?
  • What is the ideal boiling point for water?
  • How does this boiling point change in different situations?

Experimental Procedure

  1. Take two pots.
  2. Fill one pot with cold water, and one pot with warm water.
  3. Place the pots on a stove and put them on identical heat settings.
  4. Time which one heats up first.
