What step of the water cycle is when water changes back to a liquid when warm air rises and cools causing water droplets to form in clouds?

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.

Clouds are made when water droplets attach to particles of what in the air?
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.
What is the combination of water vapour and dust suspended in the sky?
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.
Who made the first water thermometer?
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.
Why do clouds form before it rains?
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.
What is a sentence using evaporation condensation and precipitation?
The processes that occur in the water cycle: precipitation: when liquid or solid water falls from clouds transpiration: water evaporating out of plants condensation: when water vapor changes into liquid evaporation: when liquid becomes gas
Choose the statement that is true clouds?
clouds are large quantities of liquid water droplets
What forms clouds and fog?
Tiny droplets of liquid water
What do clouds contain?
Clouds are visible form of moisture. They can be liquid droplets or frozen droplets of water or any other chemical suspended in the atmosphere.
What occurs when a gas particles lose enough energy to form a liquid?
condensation. eg is like in clouds, water vapour changes to water droplets ^^
What occurs when particles in a gas lose enough energy to form a liquid.?
condensation. eg is like in clouds, water vapour changes to water droplets ^^
A great amount of water vapor changes phase to become liquid water droplets in the clouds that form a thunderstorm Does this phase change release energy or absorb it?
a great amount of water vaptor change phase to become liquid water droplets in the clouds that form a thunderstorm. does this phase change release or absord energy? how do you know
How does water vapor in the air change into liquid droplets forming clouds?
condensation
Occurs when a gas cools and changes into a liquid?
When gas cools and changes into liquid, it undergoes a process called condensation. This occurs when the temperature of the gas decreases, causing its particles to lose energy and come closer together, eventually forming liquid droplets.
Are clouds composed of frozen hydrogen molecules?
No, they are large quantities of liquid water droplets.
Why do clouds form before rain?
Clouds form when water vapor condenses into tiny liquid droplets. If enough condensation occurs in a cloud then some of the droplets will grow bigger and fall as rain.
Is this a true statement clouds are large quantities of liquid water droplets?
Mostly, but clouds also contain dust particles and bits and pieces of ice, depending on how high they are. It is widely accepted that clouds are made of water droplets and water vapor
Process by which water vapor changes from gas into liquid droplets?
Condensation
