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: 150. - 130. - 110. - temperature (°C) 90. - 70. - 0. 10. 40. 50. heat added (kJ/mol) Use this graph to answer the following questions: What is the boiling point of X ? (check all that apply) What phase (physical state) of X would you expect to find in the flask after 7 kJ/mol of heat has been added? O solid O liquid O gas
