Page 5-EA Measuring Energy Changes- Page 6 Post-Lab Calculations and Analysis (Use a separate sheet of paper to ansuwer the following questions.) Part A. Temperature and Phase Changes 1. Using your data, draw a graph of temperature (y-axis) versus time (x-axis). q Excel 2. Note on the graph the temperature at which all of the ice has melted and the temperature at which the water starts to boil. 3. Are there any temperature plateaus (flat regions of the curve) on the temperature versus time graph? Name the physical property of water corresponding to each temperature plateau. 4. Was heat being added to the system during the times that the temperature remained rela- tively constant? Use the law of conservation of energy to describe what happened to the heat energy that was absorbed during this time. 5. Was heat being added to the system during the times that the temperature was rising? Use the law of conservation of energy to describe what happened to the heat energy that was absorbed during this time. Part B. Energy Needed to Melt Ice
