Question: What Is The Process Of Evaporation And Condensation?

What is the main cause of evaporation?

Evaporation happens when a liquid substance becomes a gas.

When water is heated, it evaporates.

The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor.

Heat from the sun, or solar energy, powers the evaporation process..

What is the result of evaporation?

When evaporation occurs, the energy removed from the vaporized liquid will reduce the temperature of the liquid, resulting in evaporative cooling. … Evaporation of water occurs when the surface of the liquid is exposed, allowing molecules to escape and form water vapor; this vapor can then rise up and form clouds.

What happens during condensation?

Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor. Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water.

Is boiling water an example of evaporation?

Boiling is similar to evaporation because both processes turn a liquid into a gas. … Because of the pressure difference, gas bubbles from all through the liquid are able to rise up and escape as vapor.

What is evaporation very short answer?

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.

Which process requires energy condensation or evaporation?

Energy is required to change from solid to liquid, liquid to gas (evaporation), or solid to gas (sublimation). Energy will be released to change from liquid to solid (fusion), gas to liquid (condensation), or gas to solid. Latent heat of evaporation is the energy used to change liquid to vapor.

What is the role of evaporation and condensation in water cycle?

The role of evaporation and condensation in the water cycle is A.) They recycle and redistribute the water in an ecosystem. Evaporation is the process of turning of liquid into water vapor. … If there would be no evaporation and condensation, there will be no clouds meaning rain will not also occur.

What is evaporation example?

Evaporation is defined as the process in which the state of water from liquid to gaseous or to vapour state takes place. The rate of evaporation is dependent on the temperature. As the temperature increases, the evaporation rate increases. … The melting of an ice cube is an example of evaporation.

What are 2 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…

Is condensation a spontaneous process?

Recall that the condensation of water vapor occurs spontaneously at temperature below 100°C but not above. Condensation is an exothermic process; to see this, consider that the reverse process, evaporation, obviously requires heat input.

What is the process of 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.

Is heat added or released in condensation?

A substance condenses when the pressure exerted by its vapour exceeds the vapour pressure of the liquid or solid phase of the substance at the temperature of the surface where condensation occurs. Heat is released when a vapour condenses.

What is a good sentence for evaporation?

Evaporation sentence examples. There was evaporation of water from the leaf. The annual evaporation from water surfaces is from 60 to 150 in. The test tube is tightly corked to prevent evaporation, and allowed to stand for some hours.

How can evaporation be prevented?

Cool the water down or limit its exposure to heat by keeping it in the shade, adding ice or cooling with refrigerated pipes. This lowers the kinetic energy available to the water molecules, which slows the evaporation rate.
