Question
pure sou 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 aph of the results: temperature (°C) 200. 180,- 160.- 120.- 100.- 10. What is the melting point of X ? heat added (kJ/mol) Use this graph to answer the following questions: What phase (physical state) of X would you expect to find in the flask after 7 kJ/mol of heat has been added? 0°C (check all that apply) solid O liquid Ogas 1
