The first slanted line is the substance in the solid state. The second slanted line is the substance in the liquid state. The flat line in between the two slanted lines represent the transition from the solid state to the liquid state. Hence, the melting point of the substance (transitioning point from solid to liquid) is 20 degrees Celsius.
