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 heat capacity in the gaseous phase C, (e). Substance Z is just like S except that it has a higher heat capacity in the solid phase C, (s). Select the graphs below, on the left and right, that show the results you expect for these new experiments. Substance Y (lower C, (g)) (Drag the slider to choose an image) temperature (°C) Substance S پر added heat (kJ/mol) Substance Z (higher C, (s)) (Drag the slider to choose an image)
