Do particles move faster or slower when water vapour cools and forms raindrops?

The particles move slightly faster, it has a medium attraction and pours down.

How does snow happen?
We all know that as we go higher in the atmospherethe temperature decreases. Therefore the capability of air to hold the water vapour decreases and excess of water vapour gets collected in the air at a certain height. The air, now having too much water vapour, is said to be supersaturated. Under these conditions, the water vapour condenses on the dust particles present in the air. On further cooling, the water vapour gets converted into snow particles. Crystals of snow are formed by the combination of these particles. When the air cannot bear the weight of the crystals of snow, they fall down as snow flakes and get collected on the mountains.
What can ice change to become water or vapor?
The particles in liquid water are in some degree of motion. When heated to vapor, the particles move far apart from each other, in any direction. When cooled to ice, the particles move close together and vibrate around a fixed point
What are small particles in the air around which water vapor condenses?
these small particles in the air or atmosphere is known as condensation nuclei. condensation nuclei my consist of dirt particles like grain of sand or dust, or it may be the smock,because the metrical present in the smock is also work as condensation nuclei . and for condenses water vapour requierd a platform,which it obtain from the condensation nuclei.

What does water condenses into?
Water evaporates into water vapour, and water vapour condenses into water.
Is oxygen a vapour or not?
no
What tiny raindrops are called?
condensation nuclei--for instance (water vapour)
How is particle motion related to evaporation?
KE of particles in a liquid will differ, the faster ones can escape as vapour even at temperatures lower than boiling.
Cells need energy to?
As cells gain energy (usually heat) they move faster. When particles get heated enough, they will change state. Example: boiling water results in water vapour.
How does a raindrop form?
Raindrops form around a nucleus of dust or essential oils given off by the forest canopy. Water vapour at the 'dew point' needs a seed particle for it to change state from vapour to liquid state.
What happens to the particles in a liquid when it is heated?
They begin to vibrate more quickly when a liquid is heated, it will evaporate. ie. the liquid will turn to vapour (gas). if the vapour i s collected, it will turn back to the liquid again once it is cooled (condensation) muck love, kate
Why does dust particles present in the air help water vapour to condense?
somehow
Why does a puddle evaporate more quickly on a windy day?
Because as the water molecules (little tiny droplets that are so small that you can't even see them) get heated by the sun they start to move faster and faster until they escape from the liquid and become a gas (water vapour). On a cold day or a day without sun this process is slower because the molecules move slower and find it more difficult to escape from the liquid.
What is the difference between a gas and a vapour?
A gas is the normal state for a material at given temperature while a vapour is made from some particles that have escaped from the liquid surface.
What is a vapour trail behind a jet plane made from?
Ice crystals of frozen exhaust particles.
Why is visibility reduced when it is foggy?
Fog is fine particles of condensed water vapour in the air. These particles reduce visibility similar to dirt on windows and car windshields.
What happens to the particles when water vapour changes into water?
the particle loses the energy and it goes into surrounding environment
When a gas turns solid does it give off energy or take in energy?
Well let's say that the gas is water vapour. For it to become a solid, it must first become a liquid. It does this by being cooled (it condenses) which makes it lose energy, slowing down the vibration of the particles. When it solidifies, the particles vibrate even slower, losing their energy. So here's your answer- it does neither, it just loses energy.
