# Critical Point Phase Diagram

**Critical Point Phase Diagram**. The most prominent example is the liquid-vapor critical point. Did you know that supercritical fluids can be used to dissolve and isolate substances (such as extraction of caffeine from coffee beans)?

The procedure of critical point drying is an efficient method for drying delicate samples for SEM applications. On the x-axis, I have temperature, and at any given point, this diagram will tell you whether you're dealing with a solid, so solid will be This is the critical point. The end of the "boiling curve", separating the liquid to vapor transition, is called the "critical point".

### The critical point is the end point of a phase equilibrium curve, defined by a critical pressure Tp and critical temperature Pc.

The most prominent example is the liquid-vapor critical point.

For each substance, the conditions defining the critical point are the critical temperature, the critical pressure, and the critical density. Critical points are super interesting experimentally and theoretically. So just to understand what's going on here, is that on this axis, I have pressure.
