How To Read A Phase Diagram

On the x axis i have temperature and at any given point this diagram will tell you whether youre dealing with a solid so solid will be here a liquid will be here or a gas. At these temperatures and pressures the rate at which the solid sublimes to form a gas is equal to the rate at which.

Mean Field Phase Diagram For N L As A Function Of X And G The

This is a fairly common characteristic of bimetallic alloys the copper silver system for instance has a phase diagram very similar to the one in the link.

How to read a phase diagram. If it is temperature that you are varying you can easily read off the boiling temperature from the phase diagram. The points along the line connecting points a and b in the phase diagram in the figure above represent all combinations of temperature and pressure at which the solid is in equilibrium with the gas. First lets consider the information that is displayed.

In the diagram above it is the temperature where the red arrow crosses the boundary line. If you know everything already you can take this. So just to understand whats going on here is that on this axis i have pressure.

This phase diagram phase diagram shows a typical binary system that happens to contain a eutectic. The liquid will change to a vapour it boils when it crosses the boundary line between the two areas. A phase diagram helps show what phase exist at what temperature and pressure.

Everybody remembers that the boiling point of water is 100c but thats only true at a certain pressure 1 bar. The green line marks the freezing point or transition from liquid to solid the blue line marks the boiling point or transition from liquid to gas and the red line shows the conditions under which a solid can be converted directly to a gas and vice versa. How to read a phase diagrams.

This is the phase diagram for water. In this phase diagram which is typical of most substances the solid lines represent the phase boundaries. So how do you read a phase diagram.

Boiling points melting points and sublimation points vary with pressure.
