Medical Definition of evaporation. When the hot steam comes in contact with the ice cold bottom of frying pan, it gets cooled and condenses to form drops of liquid water. Dew DEFINE. Water vapour gets added to the air (or atmosphere) by the processes of evaporation and transpiration. If the liquid substance is not evaporated correctly, then people might end up smoking both the good and the bad substances, making it unsafe and unhealthy. Expansion: A process in which an object becomes bigger in size, e.g., metals expand on heating. The Water Cycle Song by Have Fun Teaching is a Water Cycle Video that introduces the Water Cycle, including Evaporation, Condensation, and Precipitation. When a gas turns into a liquid. So, when the air containing water vapour rises to a high altitude in the atmosphere, the water vapour present in it gets cooled so much that it condenses to form tiny droplets of water.

Most of the rivers cover long distances on land and ultimately fall into a sea or an ocean. This is called snowfall, Snowfall occurs during winter in the extremely cold hilly areas of the earth. Sometimes the frozen water from the clouds also falls on the earth in the form of small, round pieces of ice called hail. Also, this chapter focuses on different types of changes like reversible, irreversible, contraction, expansion, melting, and evaporation. The process of transpiration puts a large amount of water vapour into the air. Plants take water from the soil to grow.Plants use a part of this water to make their food and retain some of it in their different parts. After all the water of salt water mixture taken in the kettle boils off, salt is left behind in the kettle. For example, we spread clothes out to dry them faster.

If such types of websites are available on internet then there is no needs of tuitions for student. This water vapour goes into air. This salt can be taken out from the kettle.In this way,  salt water mixture has been separated into salt and water by the process of distillation. It is also held by the soil. The use of process of evaporation for separating a mixture is based on the fact that liquid vaporise easily whereas solids do not vaporise easily. Very nice explanation. The process of evaporation is used on a large scale to obtain common salt from seawater. The formation of clouds involves the process of condensation. Evaporation occurs before a liquid reaches its boiling point. (4) Now as we go higher and higher from the surface of earth, the temperature decreases, it becomes cooler and cooler.

If we have a mixture of common salt and water, then we cannot separate salt from water by filtration. Answer: Threshing is a process in which we separate grain from stalks. Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. Take a glass half filled with water and add some ice to it . When the molecules of the liquid collide, they transfer energy to each other based on how they collide with each other. (1) If we take out a bottle of ice-cold water from the refrigerator and keep it on a table, then a puddle of water is formed around it after some time. This is because when the water vapour present in air around the bottle comes in contact with the cold outer surface of bottle, it gets cooled and condenses to form liquid water which then forms a puddle of water around the bottle. Question 10 In order  to clean spectacles, people often breathe out on glasses to make them wet.Explain, why, the spectacle glasses become wet? This is because common salt is completely dissolve in water and not insoluble in it. Question 3 Why do water drops appear on the outer surface of a glass containing ice-cold water?

This water vapour goes into air. Question 8 Explain why, if we take out a bottle of water from a refrigerator and keep it on a table, we notice a puddle of water around it after sometime. Enthalpy of evaporation or latent heat (h fg) This is the amount of heat required to change the state of water at its boiling temperature, into steam. The evaporation rate depends on the temperature and humidity of the air, which is why sweat accumulates more on humid days, as it does not evaporate fast enough. The dissolved substance is left as a solid residue when all the water has evaporated. Clouds DEFINE The changing of water vapour into liquid water on cooling, is called condensation.
