What is called vapour?
A vapor refers to a gas-phase material that that normally exists as a liquid or solid under a given set of conditions. … A good synonym (alternate word) for vapor is gas. When a substance turns changes from a solid or liquid into a gas, the process is called vaporization. The material is said to vaporize or evaporate.

What type of colloid is an aerosol?
Aerosol contains small particles of liquid or solid dispersed in a gas. In aerosol, the dispersion medium is gas while the dispersed phase can be both solid and liquid. Example for aerosols are smoke, fog and mist. Thus, the aerosol is a kind of colloid in which Solid/Liquid is dispersed in gas.
