Room Temperature Water Particle Diagram

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.

Room temperature water particle diagram.

This higher the pressure the higher the boiling point as the pressure forces the particles to stay together for longer. So just to understand what s going on here is that on this axis i have pressure. 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. This is the phase diagram for a typical pure substance.

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. The temperature of a system depends on the average kinetic energy of its particles. The temperature at which something boils is known as boiling point. The bubbles in boiling water are pockets of water vapour a gas escaping.

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. This graph is part of a heating curve for water. Which particle diagram represents molecules of only one compound in the gaseous phase.

As the liquid boils the temperature of the liquid remains at 100 c. We can explain this with the diagram in the figure below. This depends on the strength of forces between particles and the ambient air pressure.
