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.
