As the liquid boils the temperature of the liquid remains at 100 c.
Room temperature water particle diagram.
This depends on the strength of forces between particles and the ambient air pressure.
We can explain this with the diagram in the figure below.
A phase diagram lets you work out exactly what phases are present at any given temperature and pressure.
This graph is part of a heating curve for water.
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.
1 ionization 2 combustion 3 filtration 4 sublimation 22 at room temperature a mixture of sand and water can be separated by.
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.
This is the phase diagram for water.
So just to understand what s going on here is that on this axis i have pressure.
The bubbles in boiling water are pockets of water vapour a gas escaping.
This higher the pressure the higher the boiling point as the pressure forces the particles to stay together for longer.
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.
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.
