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: 190.- TI temperature (°C) 150. 30. heat added (kJ/mol) Use this graph to answer the following questions: What is the melting point of X ? 1°C What phase (physical state) of X would you expect to find in the flask after 19 kJ/mol of heat...

A pure sample of Substance S is put into an evacuated flask. The flask is then heated steadily and the temperature measured as time passes. The results are graphed below, in the middle (in green) Identical experiments are now run on Substance Y and Substance Z. Substance Y is just like S except that it has a lower enthalpy of vaporization AH Substance Z is just like S except that it has a higher enthalpy of vaporization AH Select the...
