True or false A rainbow is a spectrum of light that appears when the sun shines onto water droplets in the air?
True, or more correctly, when the sunlight is refracted through the water droplets.
Why would rainwater contain dissolved solids?
Traces of various solid elements such as lead, salt and sulfur may be detected in rainwater for a variety of reasons. 1. There are many kinds of substances floating in the air in the form of tiny particles, including dust, pollen grains, and pollutants such as sulfur dioxide, and lead compounds. 2. The density of water vapor is lower than that of the air, therefore water vapor goes up in the air. 3. The higher the altitude, the colder it becomes. Water vapor cools down as it ascends in the air. The molecules of the cooled water vapor are attracted to the surface of the floating solid particles. It takes billions of water molecules to form a droplet. The droplets collide with each other and merge into bigger and heavier water drops. It takes about a million droplets to make a raindrop, which finally becomes so heavy that the air cannot hold it up any longer. Then many such drops fall out of the sky, and that's how the rain forms. The tiny solid particles floating in the air are very important--they are the bases of rain drops. In fact, without solid particles, there will be no rains no matter how much water vapor there is in the air. Therefore, rainwater is not pure water, and there are many tiny solid particles within every raindrop. Some solid particles may dissolve in water, some not. In some cases a waterspout (a tornado forming over the ocean) can lift thousands to millions of gallons of sea water high into the air which can subsequently drop onto land, but this is not the normal process for rain formation.
What is the process by which water in the atmosphere is deposited as droplets on surfaces morning dew on grass?
The water vapor in the air goes from a gas state to a liquid state onto the grass.
How could you prove that the liquid condensing from exhaled air is water?
you can prove that when you exhale,water is released. hold a mirror up to your mouth.Breath onto the mirror.Describe what you see in your notebook.Then,explain how you have proven that when you exhale, water is released.
What source of energy causes the change in the water cycle?
The sun evaporates water, which condenses onto dust particles to make clouds, which precipitates to form rain
Why do clouds have dust and salt particles in them?
To make it white.-No. Dust or cloud nuclei is needed to form a cloud because the water particles need something to stick to. When a bunch of these water droplets stick together and form one, it becomes a cloud.
What is it called when you breathe onto a cold window and water droplets appear?
The water droplets are called condensation.
What are the water droplets on cars or grass in the early morning?
The water droplets known as dew form when the air temperature passes below the "dew point" and water vapor condenses from the air onto the cooler objects. When cooled, air can no longer hold as much moisture.
Compare and contrast the growth of cloud droplets and the growth of ice crystals?
Cloud droplets grow through condensation of water vapor onto aerosol particles, leading to collisions and coalescence. Ice crystals grow through deposition of water vapor onto a nuclei, forming hexagonal shapes. Ice crystals typically grow at lower temperatures and supersaturation levels compared to cloud droplets. Both processes contribute to the formation of precipitation in clouds.
When you breathe onto a cold window and water droplets appear it is an example of?
Condensation
True or false A rainbow is a spectrum of light that appears when the sun shines onto water droplets in the air?
True, or more correctly, when the sunlight is refracted through the water droplets.
What happens to water vapor when it cools then condenses around dust and salt?
When water vapor condenses around dust particles a cloud is formed
How are water droplets formed when salt sand and water are boiled together?
Filter the sand, salt, water mixture to remove the sand. Then boil the salty water to produce steam (water vapour). Then condense the steam onto a cold surface, fresh water droplets will form on the cold surface. If the steam is captured in a condenser, the steam will return to fresh water.
Why do clouds produce rain?
Clouds produce rain because water that has been evaporated needs somewhere to go. Any h20 gets evaporated. And then condensed which means for water to become a water vapor or cloud. Once so much water gets evaporated and then condensed, it has no where where else to go but down. Gravity can't hold the droplets of water that form in clouds. droplets of water fall down onto the ground. These droplets of water are known as rain.
What does dew mean?
Water droplets condensed from the air, usually at night, onto cool surfaces
What provides the energy to make water change its state in the water cycle?
The sun evaporates water, which condenses onto dust particles to make clouds, which precipitates to form rain
Why does precipitation often happen at front?
Precipitation occurs at fronts due to the change in temperature. The sudden alteration causes the water vapor to condense onto small particles of dust and other matter that is present in the atmosphere. These are called droplets. When enough water vapor has condensed onto that particle, a rain drop is formed and falls to Earth.
