🤓 Based on our data, we think this question is relevant for Professor Keller's class at MIZZOU.
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:
Use this graph to answer the following questions:
What is the melting point of X?
What phase (physical state) of X would you expect to find in the flask after 9 kJ/mol of heat has been added? (check all that apply)
