Fog forming on a mirror

Detailed explanation-1: -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.
Detailed explanation-2: -Steaming up or fogging happens when steam condenses on the mirror. Steam emerging from hot water can condense on a colder surface. That’s the reason you can see the result on a mirror instantaneously.
Detailed explanation-3: -Few examples of condensation are given below: Morning dew on the grass. Water droplets on the outer surface of cold drink bottle. Foggy car windows.
Detailed explanation-4: -Fog shows up when water vapor, or water in its gaseous form, condenses. During condensation, molecules of water vapor combine to make tiny liquid water droplets that hang in the air. You can see fog because of these tiny water droplets. Water vapor, a gas, is invisible.
Detailed explanation-5: -As the water-vapor molecules bounce around in the air, some of them come close to the mirror, which is cooler than the surrounding air. This causes the water-vapor molecules to lose heat energy (cool), slow down, and join to gether to form liquid-water droplets on the mirror. That’s called condensation.
