What is evaporation Class 9?
The process of a liquid changing into vapour (or gas) even its boiling point is called evaporation.
The wet clothes dry due to evaporation of water present in them.
Thus the fast moving particles (or molecules) of a liquid are constantly escaping from the liquid to form vapor (or gas).
How can you explain evaporation in nature?
Evaporation happens when a liquid turns into a gas. … When liquid water reaches a low enough temperature, it freezes and becomes a solid—ice. When solid water is exposed to enough heat, it will melt and return to a liquid. As that liquid water is further heated, it evaporates and becomes a gas—water vapor.
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.
How do you explain evaporation?
Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor.
How do you explain evaporation to a child?
Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam. The water vapor or steam leaves the river, lake or ocean and goes into the air.
What is the most important use of evaporation?
Evaporation is also used to concentrate liquid foods such as noodles and make condensed milk, the product of a process that removes water from milk. Similarly, pharmaceutical companies use evaporators to remove excess moisture from drugs, thus improving product stability.
What are the effects of evaporation?
When evaporation occurs, the energy removed from the vaporized liquid will reduce the temperature of the liquid, resulting in evaporative cooling. On average, only a fraction of the molecules in a liquid have enough heat energy to escape from the liquid.
Where is evaporation used in everyday life?
The melting of an ice cube is an example of evaporation. Evaporation of acetone which is used for removing nail paint is another everyday example of evaporation. Distillation is the process in which two mixtures are separated with the help of evaporation as boiling of these mixtures is involved.
Why is evaporation important in our daily life?
Evaporation in Daily Life One important example of evaporation is sweating. The sweat requires energy to evaporate off of your skin. It gets that energy from the excess heat your body is producing, in turn causing you to cool down.
What are some real life examples of evaporation?
13 Everyday Life Examples of EvaporationDrying Clothes under The Sun. One of the most common real-life examples of evaporation is drying of clothes under the sun. … Ironing of Clothes. … Cooling Down of Hot Tea and Other Hot Liquids. … Wet Floors. … Melting of Ice Cubes. … Preparation of Common Salt. … Evaporation of Nail Paint Remover. … Drying of Wet Hair.More items…
What are the 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.
When evaporation is not useful to us?
Out of many examples, there a few ones which state evaporation is not useful in some cases. Like when the sea water level is higher or when the body is dehydrated by the sun evaporates all th water from your body which can cause fatigue or even death and so on.
What is importance of evaporation?
The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor. Evaporation is a very important part of the water cycle. Heat from the sun, or solar energy, powers the evaporation process. … Once water evaporates, it also helps form clouds.
What made the water disappear?
In nature, the energy, or heat of the sun causes water to evaporate into its gaseous, or vapor, phase. … The process by which a substance changes from a liquid to a gas is called evaporation.
What is evaporation and its examples?
Evaporation is defined as the process of a liquid changing into a gas. An example of evaporation is water turning into steam.
Is Fog An example of evaporation?
The above picture, taken in Iceland, is a great example of evaporation fog. When this overlying layer of air finally becomes saturated, condensation occurs, and since the air is adjacent to the ground, the cloud that results is referred to as fog. …
What is evaporation with diagram?
Evaporation is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure. Evaporation is a fundamental part of the water cycle and is constantly occurring throughout nature.
