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: 140. 120. 100. temperature (°C) 80. - 60. heat added (kJ/mol) Use this graph to answer the following questions: What is the melting point of X ? (check all that apply) What phase (physical state) of X would you expect to find in the flask after 8 kJ/mol of heat has been added? O solid O liquid O gas
