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: temperature (°C) 50.- 30.- 10.- -10.. -30.- - 50. 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 15 kJ/mol of heat has been added? °C (check all that apply) O solid O liquid Ogas X ? d. Ar
