need help with this chemistry **Transcription for Educational Website:**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. Here is a graph of the results:(Graph Description)- The graph has the x-axis labeled as "heat added (kJ/mol)" ranging from 0 to 30.- The y-axis is labeled "temperature (°C)" ranging from 0 to 80.- The plotted line shows the temperature initially rising from 0°C to 20°C as heat is added. - The line then plateaus from about 20°C to about 60°C, indicating the melting process.- After the plateau, the temperature rises again from 60°C to 80°C as more heat is added.Use this graph to answer the following questions:1. **What is the melting point of \(X\)?** - [Enter melting point here] °C2. **What phase (physical state) of \(X\) would you expect to find in the flask after 4 kJ/mol of heat has been added?** (Check all that apply) - [ ] solid - [ ] liquid - [ ] gas

During transition of state of a substance temperature remains fixed.Answer: What is the melting point of X? Answer: 15°C What phase (physical state) of X would you expect to find in the flask after 4 kJ/mol of heat has been added? Answer: ✓ solid ✓liquid Explanation: Since we started with solid substance of X so on giving heat energy it will first convert into liquid then gas. And we know that transition of state takes place at constant temperature. So first flat horizontal line is at 15°C represents the first transition from solid to liquid. So there is two phases exist in equilibrium are solid and liquid.
