The Mpemba Effect

This essay discusses the mpemba effect and how it works. The definition of the word Mpemba is basically a question where you ask can hot water freeze faster than cold water it can be used as a science fair experiment and to solve other scientific questions.The key aspect discussed in this annotated bibliography is what the mpemba effect is what the history of the experiment is and how it is exactly used that is what it is about.
Can hot water freeze faster than cold water.I think that the temperature will change throughout the experiment at points I think the temperature will get colder than the water's temperature.The water in both cups will have different times that they will be the same temperature as the air around it.This is when you would
ask the question if the water was a different type then would that affect how fast the water would freeze.How much water would be in each cup and what kind of water would it be that can change everything about this question.I think that if the water is cleaner it can freeze faster to a point.In conclusion I think that the hot water can freeze faster than the cold water because of the water molacules when the water is cold they are grouped together but when they are heated up they,move alot faster and are all seperated leaveing them alone and alot easyer and quicker to freeze but it still depends on the type of water it is so I think that if it is tap water the amount of water put into the cups.

Would the size of the cup affect the amount of water in it?er it will take longer to freeze but if it is clean water it will freeze faster than the cold water.
If you were to put 3 cups of water into each of the cups would that affect how long it would take for the water to freeze into ice.The experiment was first tested on and put into the newspapers in 1969.(Sharon, Mollerus,para 4,2014).If you change the type of the water and the type of the cup would that make a difference with how well it freezes and how fast it would freeze in negative temperatures. Before the mpemba effect was freezing water it was how fast sugar dissolved in milk.(Sharon,Mollerus,para 3,2014).I think that the shape of the cup could possibly affect the way the water freezes in the cup
exactly

The temperature where you would be freezing the water for the experiment.During the experiment you want to make sure that the temperature where you are freezing the water stays the same till the water is fully frozen.(James,Brownridge,para3,2010).if the temperature is colder than both cups of water would it freeze faster or would it make the process slower?
I will do the experiment three times and I will set all of the temperatures different.the colder the temperature you are freezing the water in the quicker both cups of water will freeze.(Freezing Hot Water and the Mpemba Effect,para 1-2, 2007). If you set a timer for five or ten minutes you can sometimes make it a lot easier to tell when the water exactly froze and which one froze
first.

I think that the hot water freezes faster than the cold water because of the molecules in both of them. When the water is frozen all the molecules group together and stick together but when the water is heated up all of the little molecules separate and go on their own and when this happens they end up having lots of energy so they are bouncing all around in the water and since they are alone and it is a lot easier to freeze them individually because they are more exposed so every one of them will freeze super quick. if there is bacteria it would take longer to freeze because all the molecules have to be frozen and all the bacteria needs to be frozen.(Hot Water Freezes Faster Than Cold Water-and Now We Know Why,para 3-4,2013).

In conclusion it is proven that the mpemba effect can be used in many different things and for many different things in the scientific field it just depends how you use it
