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: 90. 70. temperature (°C) 50. 30.- 10. heat added (kJ/mol) Use this graph to answer the following questions: What is the boiling point of X ? What phase (physical state) of X would you expect to find in the flask after 18 kJ/mol of heat has been added? 0°C (check all that apply) O solid O liquid Ogas x 3
