What are two processes of the water cycle that occur due to heating and cooling of water?

Condensation, deposition, and freezing are processes that occur as a result of a decrease in the heat energy of water particles. When solid ice gains heat, it changes state from solid ice to liquid water in a process called melting.

What planet has water phases?


Is water denser than air?

Water has a density of 1000 kg/m^3. Therefore, at sea level, air is 784 times less dense than water. Expressed in another way, a volume of air at sea level has 0.1275% of the density of the same volume of water. Dirt is about 2.5 times the density of water.

Which air is heavier hot or cold?

Cold air is always heavier than an equal volume of hot air. “Air” is actually a mixture of several gases. By volume, dry air contains 78.09 percent nitrogen, 20.95 percent oxygen, 0.93 percent argon, 0.039 percent carbon dioxide and small amounts of other gases.

What liquid is less dense than water?

Lighter liquids (like water or vegetable oil) are less dense than heavier liquids (like honey or corn syrup) so they float on top of the heavier liquids….How Does It Work.

Material Density (g/cm3)
Light Corn Syrup 1.33
Dish Soap 1.06
Milk 1.03
Water 1.00

Is hot or cold air lighter?

The reason fr this is when air gets heated up it expands and becomes less dense than the air surrounding it also the distance between the molecules increases. So the less dense air floats in the much denser air just like ice floats on water as ice is less dense than water.

What does warm air make?

Warm fronts occur when light, warm air meets cold air. The warm air rises gradually over the cold air as they meet. As the warm air rises it cools and condenses to form clouds. Rain falls along the front as long periods of drizzle or steady rain.

How can you demonstrate that warm air rises up?

Answer 1: Hot air rises because when you heat air (or any other gas for that matter), it expands. When the air expands, it becomes less dense than the air around it. The less dense hot air then floats in the more dense cold air much like wood floats on water because wood is less dense than water

Why the hot air rises up?

As the molecules heat and move faster, they are moving apart. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward.

What happens to hot substances during convection?

Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated.

Does heat rise in liquid?

Fluids such as air and water typically become less dense when they are heated, causing them to be pushed sideways and upwards by the colder, more-dense fluid around them that is being pulled more strongly down by gravity. When water stays below 4° Celsius, it actually gets more dense as it heats up

How do we use convection in everyday life?

Everyday Examples of Convection

  • boiling water – When water boils, the heat passes from the burner into the pot, heating the water at the bottom.
  • radiator – A radiator puts warm air out at the top and draws in cooler air at the bottom.
