identifying phase transitions on a heating curve
- O GASES, LIQUIDS, AND SOLIDS Identifying phase transitions on a heating curve 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) heat added (kJ/mol Use this graph to answer the following questions: What is the melting point of X? What phase (physical state) of...
