CHART 1 – HEATING CURVE

• Why are the horizontal lines different lengths?
• Why are the slopes of the lines different?
• What are the energy changes in each segment?

CHART 2 – VAPOR PRESSURE

• What is vapor pressure and why does it change with temperature?
• How do I find the boiling point of a substance using this graph?

CHART 3 – PHASE DIGRAM
