Why doesn't the window fog up when you breathe on it on hot days?

It's because on a hot day, the window is not cold enough to condense the water in the breath that is breathed on it. The solubility of a liquid in a gas is temperature dependent, so the water in breath which is a gas mixture saturated with moisture precipitates out when it hits a cold pane of glass. Similarly when you open an oven the moisture from the food cooking lets a steam escape that will fog up your glasses.

∙ 12y agoIt doesn't necessarily occur in bad weather. What you are probably noticing is that when it rains or snows it gets colder than it usually is (air gets cooled to the dew point...snow is a little different though). That colder air will cool the air immediately on the inside of windows and condense out some of the moisture as fog. That's because the air in your house or car is much warmer and is probably holding proportionately more moisture in it. If you cool it, some of it will have to condense out.

∙ 9y agoDuring hot weather, the proportion of water becomes a gas instead of liquid. Ford requires warm and moist air to form up. Your breath inside the car is enough to cause fog on the windshield.

What are the advantages of dry ice compared with water ice of fog for a stage effect?
Dry ice forms great fog that clings to the ground when water is added to it, water ice will only form a light fog and only when there is very high humidity around and the fog doesn't last very long.
When do you see clouds?
Fog is caused by a drop of temperature when the air is moist. Air always has some moisture in it. On a warm day there will be quite a lot of moisture in the air caused by evaporation of surface water or transpiration from plants. However, if the temperature drops the moisture starts to condense into droplets big enough to cause light scatter. We call this size water droplets low to the ground - fog. Early morning fog often clears as the sun hits it due to the re-evaporation of the water.
When you breathe on a window what is it called?
It would be called condensation. The moisture in your breath "condenses" into a fog on the surface in front of you.
