What happens as water vapor cools and rises?
Because air is cooler at higher altitude in the troposphere, water vapor cools as it rises high in the atmosphere and transforms into water droplets by a process called condensation. Water vapor can also condense into droplets near the ground, forming fog when the ground is cold.
What happens when water vapor rises higher in the atmosphere and cools down?
As the water vapor rises higher and higher, the cool air of the atmosphere causes the water vapor to turn back into liquid water, creating clouds. This process is called condensation. When a cloud becomes full of liquid water, it falls from the sky as rain or snow—also known as precipitation.
What happens as water cools?
When water is cooled, the water molecules move slower and get closer together. This makes cold water more dense than room temperature water. Since cold water is more dense, it sinks in the room temperature water.
How does water Vapour turn into water?
Condensation is the process by which water vapor in the air is changed into liquid water. As condensation occurs and liquid water forms from the vapor, the water molecules become more organized and heat is released into the atmosphere as a result.
What happens to a liquid when it cools?
When a liquid is cooled to its freezing point, it transitions to its solid state. This process involves a loss of energy in the form of heat. As this happens, the molecules of a compound bond together and the liquid becomes a solid.
What happens to water vapor when it reaches the dew point?
When air has reached the dew-point temperature at a particular pressure, the water vapor in the air is in equilibrium with liquid water, meaning water vapor is condensing at the same rate at which liquid water is evaporating. Below the dew point, liquid water will begin to condense on solid surfaces (such as blades of grass)…
What happens when heat is taken away from water vapor?
If heat is taken away from water vapor, it condenses. Condensation turns water vapor into a liquid. If heat is taken away from liquid water, it freezes to become ice. Other, smaller parts of the cycle include plant transpiration.
What happens when air becomes full of water vapor?
When a pocket of air becomes full of water vapor, clouds form. The point at which condensation starts can be easily viewed in cumulus clouds, which have flat bottoms. Those flat bottoms are where vapor begins to condense into water droplets. Clouds are simply masses of water droplets in the atmosphere.
What happens to water vapor when it condenses?
When water vapor in the atmosphere loses heat and cools down, condensation happens. As the water vapor cools down and condenses, it attaches to small particles of dust floating in the atmosphere, forming tiny liquid water droplets.
