Evaporation, the process by which an element or compound transitions from its liquid state to its gaseous state below the temperature at which it boils ; in particular, the process by which liquid water enters the atmosphere as water vapour.
How would you define evaporation?
Evaporation is the process by which a liquid turns into a gas . It is also one of the three main steps in the global water cycle.
What is evaporation short?
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.
What is the definition of evaporation in Class 9?
The process of liquid changing into vapours even below its boiling point is called as evaporation. ... Thus, the fast moving particles of a liquid are constantly escaping from the liquid to form vapour.
What is evaporation in easy language?
Evaporation is when a liquid becomes a gas without forming bubbles inside the liquid volume . If bubbles are formed we are talking instead about “boiling”. For example, water left in a bowl will slowly disappear. The water evaporates into water vapor, the gas phase of water. The water vapor mixes with the air.
What are 2 examples of evaporation?
- Ironing Clothes. Have you ever noticed that ironing slightly damp clothes works best to get the wrinkles out? ...
- Glass of Water. ...
- Process of Sweating. ...
- Line Drying Clothes. ...
- Kettle Whistle. ...
- Drying of Wet Tables. ...
- Drying of a Mopped Floor. ...
- Melting a Glass of Ice.
What is evaporation example?
Drying clothes under the sun : water is removed from the clothes as water droplets get evaporated due to heat of the sun. 2. Drying up of water and potholes from streets: water gets evaporated from the potholes and puddles due to rain as it gets evaporated due to heat of the sun.
Why do we need evaporation?
Evaporation is a very important part of the water cycle . ... Once water evaporates, it also helps form clouds. The clouds then release the moisture as rain or snow. The liquid water falls to Earth, waiting to be evaporated.
What are the benefits of evaporation?
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.
How does evaporation occur in 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).
What are the effects of evaporation Class 9?
Evaporation Causes Cooling
Due to this, energy transfer occurs in the surroundings as well and this is transferred from substance to surroundings or vice versa. The change in temperature until the evaporation process will lead to cooling. Hence, evaporation causes a cooling effect.
What is Class 9 boiling point?
Hint: The temperature at which conversion of liquid on heating takes place at standard atmospheric pressure is called the boiling point of that liquid and the phenomenon is called boiling. Complete step by step solution: ... Pure water at standard pressure (1atm) boils at 100∘C .
What is another name of evaporation?
melting, dispersal, evanescence, disappearance, vanishing, escape, dissipation, fading, dehydration, desiccation, vaporization , dematerialization, dispelling, vaporescence.
Where is evaporation used?
The evaporation process is used in food processing industries to process milk, pasta, and other concentrates . Salt crystals obtained either from a natural process or from an industrial process, evaporation is used. The melting of an ice cube is an example of evaporation.
What are the types of evaporation?
- Falling Film Evaporator.
- Rising Falling Film Evaporator.
- Flash Evaporator.
- Forced Circulation Evaporator.
