Cooling Water Lab

Cooling Water Lab flat coat 1. Temperature is a measure of molecular motion the average energizing vigour of the particles. 2. Heat is a miscellanea of zippo that flows from a system at a higher temperature to a system at a lower temperature the total kinetic sinew of the particles. Hypothesis If two beakers containing different amounts of hot piss be placed into an grouch bath, then the one containing ________ ( more(prenominal) than or less) urine will cool down more quickly. Materials 2 Beakers Ice Hot Water 2 Thermometers Graph Paper Procedure 1.Copy the data put back onto your paper. 2. With stopper in place, fill basin (sink at lab table) about half full of ice. 3. brand one beaker containing 400 ml of hot 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. Construct line graphs of your data. magazine will be on the X axis and temperature on the Y axis. Data Table d epth psychology and Conclusion Questions 1. What was your hypothesis? 2. Was your hypothesis supported by your data? . What is temperature? 4. What is awake? 5. Which beaker contained more heat energy? 6. How are heat and temperature different? 7. How would the amount of energy absorbed 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 final temperature of the mixture? 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. get off pictures of a teacup and a bathtub both filled with water at the equal temperature (show coitus 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 Instructional Resources for Preservice and Inservice Chemistry T eachers. KEY analytic thinking 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 absorbed 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 bathtub both filled with water at the same temperatur e (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.
