Some particles on the surface of the liquid, which have more energy than the average, have enough energy to break away and form a gas. In a closed container, gaseous particles will also be re-joining the liquid, and the number of edexcel igcse chemistry revision of gas over the top of a liquid will be roughly constant.
The particles eventually clump together to form a liquid. The particles arrange themselves into a regular pattern and are no longer able to slide past one another.
The particles gain kinetic energy and vibrate faster and faster. Eventually, the forces of attraction between the particles are completely broken, and they are able to escape from the solid.
This happens edexcel igcse chemistry revision both air and bromine particles are moving randomly, and there are large gaps between the particles, so they can easily mix together. A few tiny crystals can produce a highly intense colour.
