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 fusion AH,. Select the graphs below, on the left and right, that show the results you expect for these new experiments. Substance Y (lower AH,) (Drag the slider to choose an image) temperature (°C) Substance S added heat (kJ/mol) Substance Z (higher AH) (Drag the slider to choose an image)
