How Clouds Form extended definition. Clouds form when moist, warm rising air cools and expands in the atmosphere. The water vapor in the air condenses to form tiny water droplets which are the basis of clouds.

To visualize this, think of a glass of ice cold water sitting outside on a hot summer day. You may have noticed that little tiny drops of water collect on the side of the glass. The cold glass of water is actually cooling the air nearby it, and it causes the water vapor that is in the air nearby to condense.

The lowest energy state for this drop occurs when the maximum number of water molecules are surrounded on all sides by other water molecules -- meaning that the drop should have the minimum possible surface area, which is a sphere.

It is water that condenses out of the air. When moisture-laden warmer air comes into contact with the cold surface of the glass, the glass absorbs heat from the air, and … if conditions are right it absorbs the heat that has maintained the water as vapor.

In all systems within which water interacts with another surface, both adhesion and cohesion are factors. When cohesion is more of a factor, the water forms spherical droplets; when adhesion is more of a factor, we get sheets of water.

it is because the water vapor from the air around the glass is giving off heat so then the glass condenses the water vapor using condensation. so that is why a glass of cold w … ater gets wet in the outside! mow you see try doing the experiment at home!

Because the surface of the glass is a lot cooler than the surrounding air. So the water vapor normally found in air condenses onto the surface of the glass. this is called con … densation. Warm moist air carries invisible molecules of water.

Let's start with the drop of water on the wax paper: It is easy to see that the drop seems to have a skin holding it into a sort of flattened sphere. It turns out that this surface tension is the result of the tendency of water molecules to attract one another (called cohesion).

Because water vapours present in air cools down and for water droplets due to cold surface of glass in which cold drink is poured. CONDENSATION.Condensation is the process of … a substance changing from a gas to a liquid. E.g when you get water on the inside of a window. The window has water vapour on it.

(Gravity squashes it, however.) This ball of water, of course, is also somewhat attracted to the wax paper (adhesion); thus, when it is tilted, the surface of the water sticks to the wax, and the drop rolls.

which process will cause droplets of water to form on the outside of a very cold glass?
The water vapor from the air around the glass is giving off heat so then the glass condenses the water vapor using condensation.
