Liquid water changes to water vapor in a process called evaporation. Evaporation is defined as the spontaneous change of liquid molecules into a gasseous state.
yes it is made of water vapor ====================== No. Water vapor is an invisible gas. You can't see water vapor. Clouds, on the other hand, can be seen. That's because clouds are composed of water droplets - liquid water, or water ice - tiny ice crystals. Either way, clouds are not invisible water vapor. Clouds can form as water vapor condenses to form tiny droplets of liquid water. These droplets can come together - coalesce - to form larger droplets. You've seen fog. Fog is a cloud at ground level. And if you've seen fog, then you've seen that clouds are composed of tiny water droplets suspended in air. Clouds can also be composed of ice crystals. (Cirrus clouds) In one case liquid water can freeze to form ice particles. It is more likely that water vapor undergoes "deposition", the opposite of sublimation. Sublimation is the process where a solid goes directly to the gas phase without going through the liquid phase. Deposition is the process where a gas goes directly from the gas phase to the solid phase.
I suspect you are thinking of clouds, but this is not an accurate description of them. It is important to realise that clouds contain droplets of liquid water, not water vapour. The droplets often condense around dust particles.
Galileo Galilei invented the first water thermometer. He created it by adding droplets of alcohol in the water. This is so the liquid is less denser and can detect changes in temperature.
there is no particular point which gas changes to liquid, because all substances have different points where gas changes to liquid. Water vapor changes to liquid at 100 degrees Celsius
The increased water content of a 'rain cloud' absorbs more of the light reflecting from the Earth, leading to a darker appearance. A less water dense one would simply reflect the light, leading to the bright, whiter clouds we associate with Summer.
Water droplets and clouds form through a process called condensation, where water vapor in the air changes into liquid droplets as it cools. This can happen when warm air rises, cools, and reaches its dew point, causing the vapor to condense onto tiny particles like dust or salt in the atmosphere. As more droplets gather, they form clouds.
Condensation
When clouds form, a gas (water vapor) condenses into liquid water droplets. This is a phase change from gas to liquid, known as condensation. As the water droplets accumulate and come together, they eventually form clouds in the atmosphere.
The water in clouds is in the form of liquid droplets. Clouds are made up of tiny water droplets that have condensed from water vapor in the air. If the temperature drops low enough, these liquid water droplets can freeze and turn into ice crystals.
clouds are large quantities of liquid water droplets
If your question is what I think it's trying to state, the answer is evaporation.
When an air mass cools from below, it reaches its dew point temperature, causing water vapor in the air to condense into liquid droplets. These liquid droplets then come together to form clouds through the process of condensation. This can lead to the formation of various types of clouds depending on the atmospheric conditions.
Tiny droplets of liquid water
Stratus clouds are made of water droplets because they form at low altitudes where the air is cooler, causing water vapor to condense into liquid water droplets. These clouds appear as a uniform layer with a smooth, gray appearance due to the small size of the water droplets and the lack of vertical development.
When water vapor changes back into a liquid, it is called condensation. This process happens when the air cools down and is no longer able to hold as much water vapor, causing the vapor to turn into liquid water droplets. Condensation is responsible for the formation of clouds, fog, and dew.
Water changes from gas to liquid through a process called condensation. When water vapor cools down, it loses energy and changes into liquid water droplets. This phase change is commonly seen in the formation of clouds in the sky.
condensation. eg is like in clouds, water vapour changes to water droplets ^^
