First of all, clouds are never made out of water vapor. Water vapor is invisible because its molecules are too far apart to optically scatter light. Whenever you see steam, mist, fog, or clouds, you are seeing small drops of liquid water or crystals of ice, and not water vapor.
Clouds can be made of water or ice crystals. Clouds come together (are made) during vaporization. The water we drink today is the same that dinosaurs once drank.
Also, can clouds combine?
In warm clouds, larger cloud droplets fall at a higher terminal velocity; because at a given velocity, the drag force per unit of droplet weight on smaller droplets is larger than on large droplets. The large droplets can then collide with small droplets and combine to form even larger drops.
When many clouds are together, they can also cast shadows on other clouds, causing the clouds to look grey. How do clouds move? The clouds and the storms they form move in the air currents, wind and jet stream.
Generally a group of clouds are all drifting in the same breeze so they won’t collide. When a wind from another direction also carrying clouds meets the first breeze then the two sets of clouds will collide, this situation is called a front.
How do clouds form in the atmosphere?
The air expands and cools, and clouds form as the temperature drops below the dew point. In other words, cold air cannot hold as much water vapor as warm air. Invisible particles in the air in the form of pollution, smoke, dust or even tiny particles of dirt help form a nucleus on which the water molecules can attach.
The water that makes up clouds is in liquid or ice form. The air around us is partially made up of invisible water vapor. It’s only when that water vapor cools and condenses into liquid water droplets or solid ice crystals that visible clouds form. A cloud on a sunny, fair-weather day.
A cloud is a lot of droplets of water and or ice crystals, depending on the temperature. The droplets float in the air molecules. Even though we don’t see them, water molecules are in the air all around us. These airborne water molecules are called water vapor.
Are clouds always drops of liquid water?
Secondly, clouds are not always drops of liquid water. Clouds can also be composed of ice crystals. In fact, the same cloud can be partly composed of water drops and partly composed of ice crystals. Clouds have no problem existing in the cold of winter, because they can just exist as ice crystals.
When in small droplet form, liquid water must be cooled well below 0 ° C (32 °F) before freezing. In fact, under optimal conditions, a pure droplet may reach -40 °C before freezing. Therefore, there are areas within a cloud were ice crystals and water droplets co-exist.
So, what happens when you pour water on a cloud?
When a rain cloud gets so full of water or mass, the water has to go somewhere and will break through the cloud and start to fall to the ground. As you pour or drip the water over the shaving cream cloud, the water will start to break through just a little bit. Observe your cloud as it gains mass and changes in composition.
Another common query is “How many droplets are in a cloud?”.
A cloud is defined as ‘a visible aggregate of minute droplets of water or particles of ice or a mixture of both floating in the free air’. Each droplet has a diameter of about a hundredth of a millimeter and each cubic meter of air will contain 100 million droplets. Because the droplets are so small,.
What happens when water vapor condenses in the air?
Just as water particles condense on grass to form dew, the tiny airborne particles of water vapor condense into liquid or ice on the surfaces of dust particles in the air. As more water vapor condenses into water droplets, a visible cloud forms. So if clouds are liquid or solid water, why don’t they immediately fall out of the sky as rain or snow?
