Does evaporation always require heat?
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..
How do you use drawback in a sentence?
Drawback sentence examplesBoiling under reduced pressure has one very serious drawback, viz. … The chief drawback of the climate is an excess of rain in some parts, especially in the west. … The only drawback to the climate is the prevalence of high cold winds in winter.More items…
What are 2 examples of evaporation?
Two familiar examples of evaporation are sweating and the rain cycle. When you are hot or undergo strenuous activity, your body produce sweat. The sweat on your skin gains energy from the body and eventually evaporates, in turn cooling you down. In weather, evaporation is demonstrated during the rain cycle.
What are the advantages of evaporation?

What is evaporation give example?

Start with evaporation. Place a full cup of water in front of a sunny window. Use a marker to make a line at the beginning water level. Each hour mark the water level and begin to look for changes. As the sun heats the water, it should begin to evaporate.
What is the heat source for evaporation?
In the water cycle, evaporation occurs when sunlight warms the surface of the water. The heat from the sun makes the water molecules move faster and faster, until they move so fast they escape as a gas. Once evaporated, a molecule of water vapor spends about ten days in the air.
What happens if there is no evaporation?
If water did not evaporate what would happen? Water would accumulate in the streams, and rivers and runoff into the ocean. Water would not cycle back up into the atmosphere and it would not rain.
What is the advantage of crystallization over evaporation?
Crystallization is the better method of separating the mixture than evaporation. This is because, on evaporation, some of the solid particles in mixture get decomposed leaving behind impurities whereas, in crystallization, pure crystals of solids are obtained.
What are the importance benefits of evaporation in the community?
Answer: The evaporation is the process by which water evaporates of converts itself into vapours and escapes into the air. Evaporation is important for communitiy because evaporation helps the plants in the process of transpiration. It helps in the process of water cycle.
