Room Temperature Water Particle Diagram

This is the phase diagram for water.

Room temperature water particle diagram.

So just to understand what s going on here is that on this axis i have pressure. The temperature at which something boils is known as boiling point. The temperature probe is connected to a vernier computer interface and a graph of temperature versus time is displayed on a computer monitor or pc. We can explain this with the diagram in the figure below.

In the cases we ll be looking at on this page the phases will simply be the solid liquid or vapour gas states of a pure substance. This is the phase diagram for a typical pure substance. This graph is part of a heating curve for water. The bubbles in boiling water are pockets of water vapour a gas escaping.

Which particle diagram represents molecules of only one compound in the gaseous phase. Water for example evaporates from an open container at room temperature 20 o c even though the boiling point of water is 100 o c. A phase diagram lets you work out exactly what phases are present at any given temperature and pressure. 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 here a liquid will be here or a gas.

As the liquid boils the temperature of the liquid remains at 100 c. The temperature increases from room temperature 25 c to the boiling point 100 c. This depends on the strength of forces between particles and the ambient air pressure.
