What provides energy for evaporation of water?
The sun
The sun provides what almost everything on Earth needs to go—energy, or heat. Heat causes liquid and frozen water to evaporate into water vapor gas, which rises high in the sky to form clouds… clouds that move over the globe and drop rain and snow. This process is a large part of the water cycle.
Is evaporation a source of energy?
A vast source of renewable energy has been sitting under our noses. Evaporating water could supply enormous volumes of clean electricity, if we can only harness it. Every day, vast amounts of water evaporate from lakes and rivers, powered by heat energy from the sun. The scale of this energy is considerable.
Does water always need heat to be evaporated?
Heat (energy) is necessary for evaporation to occur. Energy is used to break the bonds that hold water molecules together, which is why water easily evaporates at the boiling point (212° F, 100° C) but evaporates much more slowly at the freezing point.
Where is most water found on Earth?
the oceans
The vast majority of water on the Earth’s surface, over 96 percent, is saline water in the oceans. The freshwater resources, such as water falling from the skies and moving into streams, rivers, lakes, and groundwater, provide people with the water they need every day to live.
When water is warmed by the sun it?
evaporation
When water at the ocean’s surface is heated by the Sun it gains energy. With enough energy, the molecules of liquid water change into water vapor and move into the air. This process is called evaporation.
Is evaporated water always pure?
As a result, when the water vapor condenses to become water again, it is relatively pure. The evaporation and condensation are the key terms that help water purifying. While these processes occur during the water cycle, it can also be used to purify water for drinking or industry use.
What left behind when distilled water is evaporated?
Answer: Nothing is left behind.
