**Title: Understanding Heat and Phase Changes of a Pure Substance****Introduction:**A pure solid sample of Substance X is put into an evacuated flask. The flask is heated at a steady rate, and the temperature recorded as time passes. The graph below illustrates the results of this experiment.**Graph Analysis:**- **Graph Details:** - **X-axis (Horizontal):** Heat added (kJ/mol) - **Y-axis (Vertical):** Temperature (°C) - **Graph Description:** - The graph shows three distinct segments: 1. The temperature remains constant initially as heat is added (0 to 10 kJ/mol), indicating a phase change. 2. The temperature then rises steadily (10 to 30 kJ/mol), showing heating in a single phase (liquid). 3. It levels off again at a higher temperature, marking another phase change (30 to 40 kJ/mol).**Questions:**1. **What is the boiling point of X?** - Answer choices provided: Enter the temperature in °C.2. **What phase (physical state) of X would you expect to find in the flask after 17 kJ/mol of heat has been added?** - Answer choices: - Solid - Liquid - Gas**Instructions:**Use the graph to deduce when these phase changes occur and accurately answer the questions above. Click ‘Check’ to verify your answers.**Conclusion:**This experiment helps in understanding how a substance transitions between solid, liquid, and gas phases with the application of heat, by analyzing temperature changes plotted against heat added.**Resources:**- For further reading and detailed explanations, please refer to our educational resources section.
