The mirror in the bathroom during shower becomes foggy because water vapour in the air hits the cooler surface of the mirror. This process is called as____________.
Condensation
Condensation is the process by which water vapour in the air is changed into liquid water. In other words, the water in the air, a gas is known as water vapour, from your hot shower cooled when it met the surface of the cold mirror. This caused the water vapour to condense, or turn into its liquid form. You notice it as moisture or beads of water and fog that has formed on the mirror.
