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.

Question
To ensure that you are not confused, I attached what the experiment was about. I highly recommend you read through it before going to the questions. file:///Users/michaelzheng/Downloads/MeasuringEnergy%20(1).pdf
**Data Table A: Temperature and Phase Changes** - **Measuring Energy Changes** **Student Information:** - Name: Michael Zhang - Class/Lab Period: [Field left blank] --- **Time (min) | Temperature (°C) | Notes** 0 | -0.4 | Solid Ice 1 | -1.7 | 2 | 1.8 | Melting starts 2.5 | 2.5 | 3 | 4.1 | 4 | 4.1 | 5 | 4.4 | 6 | 5.1 | 7 | 18.2 | 8 | 18.2 | 9 | 46.5 | 10 | 68.9 | 11 | 65.3 | 12 | 82.5 | 13 | 90 | 14 | 95.1 | Starts bubbling 15 | 97.5 | 16 | 99.2 | 17 | 99 | 18 | 99 | 19 | 100.1 | 20 | 99.8 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | --- **Observations:** - Initial temperature recorded at 0 minutes was -0.4°C, indicating solid ice. - Melting commenced at 1.8°C by the 2-minute mark. - Around 14 minutes, bubbling was observed as the temperature climbed to 95.1°C, indicating boiling. This table documents the progression from solid ice through melting, heating of water, and into the boiling phase, noting significant temperature points and phase changes.

**Measuring Energy Changes - Page 6** **Post-Lab Calculations and Analysis** *(Use a separate sheet of paper to answer the following questions.)* **Part A. Temperature and Phase Changes** 1. Using your data, draw a graph of temperature (y-axis) versus time (x-axis). 2. Note on the graph 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 corresponding to each temperature plateau. 4. Was heat being added to the system during the times that the temperature remained relatively 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** (*This section is cut off in the image and cannot be fully transcribed.*) **Additional Notes** - Handwritten note: "Use Excel"
