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

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 …show more content…
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

    This activity helped the children understand that temperature can affect the state of a substance as it showed that the water was liquid in room temperature but turned to solid ice in the colder temperature of the freezer which is important when following the national curriculum for science as it states that children should be taught to 'compare and group materials together, according to whether they are solids, liquids or gases and to observe that some materials change state when they are heated or cooled, and measure or research the temperature at which this happens in degrees Celsius (°C)'. I know that this worked because during the activity I asked the children around the room what the temperature needs to be like to melt the ice to water and water to ice, I asked which was the liquid and which was the solid and I what would happen to the water when we put it in the freezer.…

    In my science project I will be doing “What is the fastest ways to cool soda?”. I believe, that the salted ice water bath will be the most effective one and cool the sodas the fastest. The salted ice bath with water can lower the temperature of the soda to 44 degrees in 5 minutes. There are several ways that I could cool soda. Some of the most popular methods to cool are in a salted ice bath with water, ice bath no water, and the freezer. I will be testing these ways with different types of soda each time with 3 trials.…

    Heat of Fusion for Ice

    • 5 Pages

    This lab report is a step by step process in calculating the heat of fusion for ice and to compare the differences between salt added to room temperature water and salt added to icy water. To calculate heat of fusion, one must understand heat of fusion. Heat of fusion is the amount of heat required to convert a mass of a solid at its melting point into a liquid without an increase in temperature. As difficult as this may sound, this experiment can be carried out with minimal equipment. The following equipment was needed, a 100mL graduated cylinder, a calorimeter, a digital thermometer, a calculator, water, and ice cubes.…

    Abstract: The purpose of this experiment is to study the energy changes associated with the phase changes of water. In this experiment we know the water is gaining energy so we know the heat is going to be positive and we can use the equation MCΔT to find the energy change. The specific heat will be 1 and we just have to measure the water to find the mass and take the temperature before and after we start to find the energy change.…

    But, a mixture of 20% NaCl and liquid water will have a lower freezing point (2 degrees Fahrenheit) than a mixture of 10% NaCl and liquid water (4). The 20% solution will then melt the ice much faster (though it isn't practical)(4). The material that melts ice the fastest is the material that dissolves into the greatest number of particles in a solution of that material and liquid water(4). It is important to learn how fast ice melts in different liquids because the Earth is currently going through global. If someone was able to find a way to keep ice from melting then maybe they could find a way to keep the polar ice caps from melting. Which could keep various animals from going extinct.If I place the ice in each liquid when they are at room temperature then I think the ice will melt fastest in the saltwater. When I first thought about which liquid would melt the ice the fastest I originally thought it would be the Pepsi because of the carbonation. But when I did research I found that the saltwater actually melted the ice melt the fastest. Which is one of the main reasons salt is put down on the ground when there is snow or ice on the…

    Approximately 15-20 grams of cyclohexane was added to the freezing-point tube and its total mass was calculated so that the exact mass of cyclohexane could be determined. A large beaker that was considerably bigger than the freezing-point tube of cyclohexane had its mass noted. Two holes were placed in a cork which was an appropriate diameter for the freezing-point tube. The cork was then placed in the freezing point tube and its total mass was noted. A dry thermistor and a dry stirrer were inserted into the tube through the two holes in the cork. It was assured that both the thermistor and the stirrer were immersed in the cyclohexane in the tube. The big beaker was filled with a large amount of ice and deionised water. The solution of cyclohexane was continuously stirred until it reached a uniform temperature. The freezing point of cyclohexane was determined by recording the time it took for the cyclohexane to freeze. The solution was then removed from the ice and allowed to return to its original temperature. This course of action was repeated at least three times and the average value was taken for the freezing point of cyclohexane. The exact same routine was used, except approximately 0.1 gram of benzoic acid was added to the freezing point tube. The freezing point was calculated for the solution of the predetermined mass of cyclohexane and 0.1 grams of benzoic acid. Again, it was completed a minimum of three times and the average of these values was taken. This was repeated two more time times and the mean freezing point values for each of these measurements were determined. This meant that there was data for at least three solutions as well as that of the pure…
