A mirror is likely to turn cloudy if you breathe on it. The moisture on your breath condenses on the cold surface of the mirror.
I think you are refering to "dew".
Because clouds occur when water condenses from water vapour to tiny water droplets. Water condenses when it is cold enough, and higher up in the atmosphere, it is colder.
because mirrors are cold
In the night when it is cold, the water vapour (otherwise known as dew) condenses when it makes contact with the car. Hope this helps!

A mirror is likely to turn cloudy if you breathe on it. The moisture on your breath condenses on the cold surface of the mirror.
It provides heat to the surface it condenses to. That is why gas condenses on cold surfaces.
What you see is not steam. It's better to call it fog ... a cloud of tiny water droplets in the air. They form around anything cold, for the same reason that mist condenses and collects on a cold glass of soda or a cold mirror, and that you see your breath outside on a cold day. The cold object cools the air around it, whereupon the ability of the chilled air to hold water vapor is reduced, and some of the water vapor condenses out of the air, into the liquid state.
No. The steam from a hot shower fogs the mirror.
Water vapor in your breath condenses when it contacts cold air. (It looks like steam.)
When the warm air from your lungs meets the very cold air of winter it condenses into visible water vapour. This is the steam you see.
It really depends on the temperature of the steam and temperature of the cold surface. 250 degree steam hitting a 50 or 60 degree surface will just turn back into water and droplets can be seen almost immediately. 1000+ degree steam hitting a frozen surface may cause a loud bang and eventually turn back into water.
Cold air holds less moisture than warm air. When you run the shower with hot water, the moisture condenses on the cold mirror surface causing it to fog up. If you run the shower cold, the mirror will not fog up.
the water molecules in your breath condenses as moisture on the glass.
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
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.
