What is condensation? How are clouds formed?

Question

Also, what experiments could i use to test cloud formation

Answer 1

condesnation is water vapor in the air turning into a liquid of a surface. Such as when a cold glass seems to "sweat" on a humid day
Clouds for the same way.
Small dust particles in the air act as a collection place they are called condesation nuclei. Water vaopr from the air cools down enough to reach the point it can condense this vapor finds these partricles and turns to licquid water. However the drops are so small that they can remain afloat in the sky.

If you have every walked thru fog you have touched a cloud

There are many experiments youcan do for this
The cold glas in a humid place works but if you really want to make a cloud.

This site is good for it

Answer 2

Clouds form by water droplets forming around small particles of dust in the air or close to the ground. This is called "condensation nuclei." Once many of these nuclei join, a cloud is formed.

Answer 3

The process of change of state of matter from vapour to liquid is called condensation. Condenstion of water vapour in the atmosphere produces clouds which is explained below.
Atmospheric air always contains some water.It is usually in the form an invisible gas called water vapour.When such a humid air is warm and if it rises,it expands and cools.Cold air cannot hold as much water vapour as warm air. so,some of the water vapour condenses on tiny pieces of dust(condensation nuclei) that are always available in the atmosphere, to form tiny droplets.Millions of such water droplets come together to form a visible cloud.
