This corresponds to the high peak and the low peak on the boiling curve.
2.
These lines emanate either from the critical point, or from the liquid vapor boundary ( boiling curve ) somewhat below the critical point.
3.
The critical heat flux is an important point on the boiling curve and it may be desirable to operate a boiling process near this point.
4.
This is observed on the graph as a change in the direction of the gradient of the curve or an inflection in the boiling curve.
5.
There can be "'maximum-boiling azeotropes "', where the azeotrope temperature is at a maximum in the boiling curves, or "'minimum-boiling azeotropes "', where the azeotrope temperature is at a minimum in the boiling curves.
6.
There can be "'maximum-boiling azeotropes "', where the azeotrope temperature is at a maximum in the boiling curves, or "'minimum-boiling azeotropes "', where the azeotrope temperature is at a minimum in the boiling curves.
