Cooling Water Lab

Cooling Water Lab Background 1. Temperature is a measure of molecular motion the average kinetic efficiency of the particles. 2. warmheartedness is a form of readiness that flows from a system at a higher temperature to a system at a lower temperature the derive kinetic energy of the particles. Hypothesis If two beakers containing different amounts of intent urine are placed into an ice-skating rink bath, then the one containing ________ ( more(prenominal) or less) pissing will cool down more quickly. Materials 2 Beakers Ice bitter Water 2 Thermometers Graph Paper Procedure 1.Copy the data hedge onto your paper. 2. With stopper in place, fill basin (sink at lab table) just about half full of ice. 3. Place one beaker containing 400 ml of hot body of body of water and one beaker containing 100 ml of hot water into the ice bath. 4. Record the temperature of each beaker every two minutes for twenty minutes. 5. throw line graphs of your data. Time will be on the X bloc and temperature on the Y axis. Data Table Analysis and Conclusion Questions 1. What was your supposal? 2. Was your hypothesis supported by your data? . What is temperature? 4. What is raise up? 5. Which beaker contained more lovingness energy? 6. How are enkindle and temperature different? 7. How would the amount of energy sorb by melting 10 grams of ice compare with the energy released by freezing 10 grams of water? 8. If you mixed 20. 0 ml of 20. 0 oC water with 20. 0 ml of 60. 0 oC water, what would be the concluding temperature of the categorisation? 9. If you mixed 10. 0 ml of 20. 0 oC water with 30. 0 ml of 60. 0 oC water, what would be the final temperature of the mixture? 10.Draw pictures of a teacup and a bathtub both change with water at the same temperature (show recounting particle movement). Which contains more heat? 11. A candle and a bonfire both burn at about the same temperature. Compare the heat content of each. Some material adapted from ChemSource Instruct ional Resources for Preservice and Inservice Chemistry Teachers. get word Analysis and Conclusion Questions 1. What was your hypothesis? Answers will vary. 2. Was your hypothesis supported by your data? Answers will vary. 3. What is temperature? easure of the average kinetic energy of the particles in a sample of matter 4. What is heat? measure of the total kinetic energy of the particles in a sample of matter 5. Which beaker contained more heat energy? The beaker containing 400 ml. 6. How are heat and temperature different?7. How would the amount of energy jailed by melting 10 grams of ice compare with the energy released by freezing 10 grams of water? It would be the same. 8. If you mixed 20. 0 ml of 20. 0 oC water with 20. 0 ml of 60. 0 oC water, what would be the final temperature of the mixture? 0. 0 oC 9. If you mixed 10. 0 ml of 20. 0 oC water with 30. 0 ml of 60. 0 oC water, what would be the final temperature of the mixture? 50. 0 oC 10. Draw pictures of a teacup and a ba thtub both filled with water at the same temperature (show relative particle movement). Which contains more heat? Pictures the bathtub. 11. A candle and a bonfire both burn at about the same temperature. Compare the heat content of each. Bonfire has more heat.
