Evaporation

The surrounding gas must not be saturated with the evaporating substance. When the molecules of the liquid collide, they transfer energy to each other based on how they collide with each other. But warming increases the evaporation of ocean water, which could increase the snowfall on the Arctic and Antarctic ice sheets, remove water from the ocean, and lower sea level.


The change of a liquid into a vapor at a temperature below the boiling point. When this happens, the average kinetic energy of the liquid is lowere and its temperature decreases.

It can be easily visualized when rain puddles “disappear” on a hot day or when wet clothes dry in the sun. In these examples, the liquid water is not actually vanishing—it is evaporating into a gas, called water vapor. Not all of the molecules in a liquid have the same energy.


When you have a puddle of water (H O) on a windy day, the wind can cause an increased rate of evaporation even when it is cold out. Evaporation happens on a global scale. 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. How to use evaporate in a sentence. A stricter definition of boiling point is the temperature at which the liquid and vapor (gas) phases of a substance can exist in equilibrium.


Ever noticed how water disappears from a glass if you leave it sitting on your counter? Movement directly from solid to vapor phase is called sublimation. It is commonly used to concentrate solutions of nonvolatile solutes and volatile solvents.


If the solution contains dissolved solids, the resulting strong liquor may become saturated so that crystals are deposited. To evaporate is to remove moisture by means of heat, forced ventilation, or the like, and thus to produce condensation or shriveling: to evaporate milk, sliced apples. Water boils at 2degrees Fahrenheit or 1degrees Celsius, but begins to evaporate at degrees Fahrenheit or degrees Celsius, only slowly. As the temperature increases, the rate of evaporation also increases.


Water and other liquids evaporate at different rates. These rates are influenced by the temperature, humidity, air flow and surface area of the liquid that is exposed to the air. Synonyms for evaporation at Thesaurus.


Find descriptive alternatives for evaporation. Unlike evaporation , distillation is not a naturally occurring process.

However, phase changes from liquid to gas and back to liquid occur during distillation. Information about evaporation from the DK Find Out website for kids. Improve your knowledge on what evaporation is and learn more with DK Find Out. Vaporization, conversion of a substance from the liquid or solid phase into the gaseous (vapour) phase. If conditions allow the formation of vapour bubbles within a liqui the vaporization process is called boiling.


Direct conversion from solid to vapour is called sublimation.
