Freezing+Water--James

Myth (brief description of myth) The myth that I am doing the myth that finds out can HOT water freeze faster then COLD water.

My Research For my research I have found out that some tests are successful and some tests were not. Because I looked up the MPEMBA effect and as I looked through the pages of results I found multiple sites telling me about test success and I found multiple sites telling me about tests not being successful. The range of the temperature 65oF to 80oF. The water molecules start to move and get smaller. Because the molecules in the warm water get smaller quicker than the the cold water molecules. A thermometer is a glass tube with a water like liquid that rises if the temperature gets warmer and goes down if the temperature gets colder. To determine which one freezes first you check on the water every 15 minutes until one of them is completely frozen.

Research (questions and answers): Vocab
 * Temperature: A measure of the average kinetic energy of participles in a sample of matter.
 * Freezing: To pass from liquid to the solid state by loss of heat.
 * Melting: To be changed from a solid to a liquid state especially by the application of heat.
 * Molecules: The simplest unit of a chemical compound that can exist, consisting of two or more atoms held together by chemical bonds.
 * Solid: Of definite shape and volume; hot liquid.
 * Liquid: The state of matter in which a substanance exhibits a characteristic readiness to flow, little or no tendancy to disperce.
 * Water(and its chemical Formula): A body of water such as a sea, lake, or river.
 * Kinetic Energy: Energy of motion. The energy of an object is the energy it possesses because of its motion.
 * Thermometer: An instrument for measuring temperature, often a sealed glass tube that contains a column of liquid.

Small Scale Procedure Question: Can Hot water freeze faster than Cold water? Constant Variable: The amount of water in the beakors. Independent Variable: Which one freezes first. Dependant Variable: The temperature of the water. My Hypothesis: If the hot water freezes first, then I want to know if the cold water is close to freezing, because if not I know that the Mpemba affect was correct. Materials: 2 beackors 200ml of water A microwave A freezer Procedure: From the research that I have done I have found out that __HOT__ water will freeze faster than __COLD__water thanks to the Mpemba affect. ( The **Mpemba effect** is the observation that warmer water sometimes freezes faster than colder water. Although the observation has been checked, there are many explanations to this scientific explanation for the effect).
 * 1. Fill up both beackors with 100ml of water. **
 * 2. Put the hot water in the microwave for 10sec. **** 3. Check temperature of the hot water beackor to see if temperature is at 80 degrees, check to see if the cold water beackor is 65 degrees. **** 4. If not dump out and try again by setting to different time. **** 5. Put both Beackors A and B in the freezer. **** 6. Check on them every 15min. **** 7. Record data as progressess. (check for both frezzing and temperature). **** 8. Stop data collection when eather hot or cold water is completely frozen. **
 * Small Scale Conclusion: **** After my tests were completed I found out that the HOT water froze faster then the COLD water. ** **Because while the hot water was frozen the cold water was still freezing, I know this there was bubbles moving around in the cold water.**
 * Small Scale Conclusion**
 * After my tests were completed I found out that the HOT water froze faster then the COLD water.**
 * Because while the hot water was frozen the cold water was still freezing, I know this there was bubbles moving around in the cold water.**


 * LARGE SCALE PROCEDURE**
 * For my large scale test I will be testing to see if a gallon of Hot water will freeze faster than a gallon of cold water.**
 * My question is Will Hot water freeze faster then the cold water if i change the quantity of water.**
 * My Independant Variable is:** the temperature (80oF hot and 65oF cold).
 * My Dependant Variable is: I am watching to see if the hot water still frezzes first.**
 * My Constant Variable is: Checking on the water every 15min.**
 * My Hypothesis is: If I change the water quantity, then I am expecting the hot water to still freeze first because I think that it depends on the waters temperature more then the quantity but I am expecting the hot water to freeze first based on the quantity of water I use.**
 * ITEMS I WILL NEED**
 * 2 milk jugs
 * A thermometer
 * A freezer
 * A microwave
 * Steps to my procedure**
 * 1. Fill up both milk jugs with tap water.**
 * 2. Put jug A in the microwave for 10sec.**
 * 3. Check temperature of jug A to see if temperature is at 80 degrees, check to see if jug B is 65 degrees.**
 * 4. If not dump out and try again by setting to different time.**
 * 5. Put both jugs A and B in the freezer.**
 * 6. Check on them every 15min.**
 * 7. Record data as progressess. (check for both frezzing and temperature).**
 * 8. Stop data collection when eather hot or cold water is completely frozen.**


 * LARGE SCALE CONCLUSION**
 * After my tests were done we found out which one froze completely because my friend was only able to break the cold water jug the hot water jug was completely solid.**
