Fog appears on bathroom mirrors like how your hot breath appears on glass when you breathe on it. The hot vapor in the air mixes with cool glass and fog appears. In other words, water vapor condenses on a smooth, cold surface creating condensation (steam).

∙ 12y agoThe warm water turns into vapor in the air because the pressure of the air is below the saturation pressure of the warm water at that temperature. The water evaporates. Then the water vapor moves throughout the bathroom and comes in contact with the mirror. The mirror is still at room temperature so it cools the water vapor down (past it's dew point temperature) which turns the vapor back into liquid water on the mirror.
The reason there is more water on the mirror is because glass and ceramics (the toilet) have a higher heat conductivity then other materials in the bathroom so it cools the vapor down and condenses it much faster.

∙ 9y agoBecause it is a cold surface. When you bath you increase the amount of water vapor in the air in the bathroom and the cold surface of the mirror causes this dissolved water to come out of solution in the air and settle on the mirrors surface. Just like water forming on the outside of a glass full of ice.

Part of the water vapor evaporates and atomizes in the air during bathing, when the water vapor encounters the cold mirror, it will condense into fog.

What is it called when a mirror fogs up?
Actually, everything fogs up. You just can see it better on the mirror. When you take a hot shower, it produces steam and this steam will rise in the room and then cool off and descend to the ground. As it moves, it sticks to all solid surfaces, the walls, cieling, the sink, the toilet, etc., leaving a layer of moisture on everything. Its just more evident on the mirror or a window.
How will you show that your breath contians moisture?
You could exhale onto a mirror. The moisture in your breathe condenses on the mirror to form the "fog" that you see. Be quick though because the condensations evaporates very quickly. You can get a similar effect by taking a very warm shower, with nowhere to escape, the steam condenses on the mirrors or tile i your bathroom, and makes it moist or "foggy".

Why does the bathroom mirror mists up when you have a shower?
The water vapours spread all over the bathroom when we take bath. They are on the walls, on the mirror and everywhere. However they are easily visible on the mirror as the surface is smooth and water vapours make it difficult to see clearly. Taking showers creates a humid environment. The warm water vapor permeates the air. The mirror, and walls and everything else in the bathroom, are cooler than the air, and the moisture condenses on them. It is the same affect as water condensing on the side of your cold drink on a hot day. same thing when you are in the kitchen
