Research Question Generation

Investigating the 'Mpemba Effect': Can Hot Water Freeze Faster than Cold Water?

Link to question

What is the project about?
The goal of this project is to investigate the question, "Can hot water freeze faster than cold water?" Thorough background research, a precise formulation of the hypothesis, and careful experimental design are especially important for the success of this experiment.

Where do we conduct the experiment?
At home or in school under a constant environment and temperature so as to not effect the results.

When do we conduct the experiment?
When we have come up with a plan on how to do the experiment and we have all the equipment needed.

Why does the 'Mpemba Effect' occur?
Hot water cools faster because of the bigger difference in temperature between the water and the freezer, and this helps it reach its freezing point before the cold water reaches its natural freezing point, which is at least 5°C lower.

Which freezes faster according the the 'Mpemba Effect'?
Hot water.

How do we conduct the experiment?
We have to put 2 cups of water, hot and cold respectively,  in the freezer and see which freezes faster.
