So just to understand what s going on here is that on this axis i have pressure.
Room temperature water particle diagram.
As the liquid boils the temperature of the liquid remains at 100 c.
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.
This higher the pressure the higher the boiling point as the pressure forces the particles to stay together for longer.
This is the phase diagram for a typical pure substance.
This graph is part of a heating curve for water.
The temperature of a system depends on the average kinetic energy of its particles.
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.
The temperature at which something boils is known as boiling point.
This depends on the strength of forces between particles and the ambient air pressure.
The temperature increases from room temperature 25 c to the boiling point 100 c.
1 ionization 2 combustion 3 filtration 4 sublimation 22 at room temperature a mixture of sand and water can be separated by.
Which particle diagram represents molecules of only one compound in the gaseous phase.
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 water.
