Room Temperature Water Particle Diagram

Which particle diagram represents molecules of only one compound in the gaseous phase.

Room temperature water particle diagram.

The bubbles in boiling water are pockets of water vapour a gas escaping. The temperature of a system depends on the average kinetic energy of its particles. This graph is part of a heating curve for water. As the liquid boils the temperature of the liquid remains at 100 c.

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

The temperature increases from room temperature 25 c to the boiling point 100 c. 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. A phase diagram lets you work out exactly what phases are present at any given temperature and pressure. This depends on the strength of forces between particles and the ambient air 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. 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. This is the phase diagram for a typical pure substance.
