This depends on the strength of forces between particles and the ambient air pressure.
Room temperature water particle diagram.
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 is the phase diagram for water.
The temperature of a system depends on the average kinetic energy of its particles.
We can explain this with the diagram in the figure below.
The temperature at which something boils is known as boiling point.
Which particle diagram represents molecules of only one compound in the gaseous phase.
This higher the pressure the higher the boiling point as the pressure forces the particles to stay together for longer.
1 ionization 2 combustion 3 filtration 4 sublimation 22 at room temperature a mixture of sand and water can be separated by.
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.
As the liquid boils the temperature of the liquid remains at 100 c.
This graph is part of a heating curve for water.
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 increases from room temperature 25 c to the boiling point 100 c.
The bubbles in boiling water are pockets of water vapour a gas escaping.
