Condensation occurs when anything significantly cooler than the air comes in contact with it. This includes the water found on a surface of a bottle of refrigerated water and also includes the storms found almost always along a cold front. If the air has humidity in it, the small droplets that comprise the humidity, condenses into larger water particles when it comes in contact with cooler air or a cooler surface.

Do warm and cold air make rain?
It depends on the amount of moisture present. If there is enough the warm air mass, which is usually moister, gets lifted, causing it to cool and the moisture in it to condense.
Suggest an activity to show that air contains moisture?
Cool a sheet of metal and leave it in the room, if the air contains water vapour it will condense on the cold metal.
Why does moisture gather outside of a glass of cold water on a warm day?
The cold glass cools the air close to the outside of the glass and causes the moisture in the air to condense on the outside of the glass when the molecules in the air come close enough together to touch one another..
Does a ceiling fan take the moisture out of a room in the winter?
No, the ceiling fan will not get the air temperature cold enough to condense the moisture in the air from a gas to a liquid. The only thing that takes the moisture out of air in the room is a dehumidifier. The second choice is an exhaust fan vented to the out side of the building. With an exhaust fan the air has to be replaced by new air. If the humidity of the outside air is the same or higher that the air inside then the exhaust fan will not do the job.
Why do thunderstorms occur on humid days?
Moisture is essentially the fuel of thunderstorms. Moist air contains water vapor, which in turn holds large amounts of energy in the form of latent heat. Thunderstorms develop when this air rises and cools, causing the moisture to condense and release this stored energy.
What is one thing needed for condensation to occur?
There must be moisture in the air. When cooled, the water vapor in the air becomes liquid water- but if there is no moisture, then it cannot condense.
Why does air going up allow clouds to form?
When air rises it decompresses and cools. The cooling can cause moisture in the air to condense.
Do clouds form when air rises and then the become saturated?
Typically, yes. As air rises it cools, which can cause moisture in it to condense.
Why does precicpitation occur when warm air rises?
When air rises in the atmosphere it decompresses and cools. This can cause moisture in the air to condense and form precipitation.
Do warm and cold air make rain?
It depends on the amount of moisture present. If there is enough the warm air mass, which is usually moister, gets lifted, causing it to cool and the moisture in it to condense.
Why are tornadoes cone shaped?
The visible funnel of a tornado is the result of moist air being pulled into the vortex. The low pressure in the tornado causes a temperature drop, which in turn causes the moisture to condense. Temperature continues to drop as the air rises in the tornado, causing more moisture to condense at higher altitudes..
Suggest an activity to show that air contains moisture?
Cool a sheet of metal and leave it in the room, if the air contains water vapour it will condense on the cold metal.
When is condensation seen outside?
I think your referring to Dew point. When the outside temperature is cool enough for moisture in the air to condense on the ground. That has to do with humidity and ambient air temperature
Why does moisture gather outside of a glass of cold water on a warm day?
The cold glass cools the air close to the outside of the glass and causes the moisture in the air to condense on the outside of the glass when the molecules in the air come close enough together to touch one another..
Where does the steam from under the streets come from and what purpose does it serve?
Warm air (at least warmer than the outside temperature) rising out of the storm sewers causes moisture in the air to condense.
If you wanted to make water vapor come out of the air so you can drink it what should you do?
have an object surrounded by the air at a lower temperature that the dewpoint so that the moisture would condense on the surface.
