Since evaporation takes place from the surface of the liquid, the greater the exposed surface area, the faster the rate of evaporation. With a larger surface area, more heat and wind can assist in the evaporation of the water when the water is on the table.

Molecules contained in a liquid evaporate from the surface area. This means that the larger the surface area, the faster the rate of evaporation. The amount of water left in the bowl is much less than is left in the glass, due to the difference in surface area.

The rate of evaporation depends on the liquid’s exposed surface area (faster when increased), the humidity of surroundings (slower when increased), the presence of wind (faster when increased) and the temperature (faster when increased).

Evaporation increases with an increase in the surface area If the surface area is increased, then the amount is of liquid that is exposed to air is larger. More molecules can escape with a wider surface area.

Factors That Affect the Rate of Evaporation

• temperature of the liquid. A cup of hot water will evaporate more quickly than a cup of cold water.
• exposed surface area of the liquid.
• presence or absence of other substances in the liquid.
• air movement.
• concentration of the evaporating substance in the air.

Which of the following does not affect the rate of evaporation (1) wind speed (2) temperature (3) surface area (4) insoluble heavy impurities. ​ The evaporation rate is dependent on certain variables such as temperature, surface area, wind speed, etc. But not depend on the mixture of absolute heavy impurities.

The evaporation rate is an important factor that influences the effect of evaporative cooling of permeable pavements. It is determined by a complex system of factors, such as air temperature, relative humidity, water temperature, moisture content, air void content, size, and structure.

Evaporation increases with the increase in wind speed. Vapour particles move away when the speed of wind increases. This leads to a increase in the amount of water vapour in the atmosphere.

Evaporation increases with increase in wind speed. With the increase in wind speed, the particles of water vapour move away with the wind, decreasing the amount of water vapour in the surrounding. Hence, clothes dry faster on a windy day.

Higher winds will continue to supply drier air from aloft to the water surface and this allows for a greater amount of evaporation. A higher wind also churns the water (waves, splashing) and this helps lead to a greater surface area in which evaporation can occur from the water surface. 4.

When common salt is added to water then surface is occupied by the solvent as well as non-volatile solute particles. So, the escaping tendency of solvent particles decreases and thus the evaporation of water decrease. Therefore, other option (b), (c) and (d) will decrease the evaporation of water.29. aug 2020.

Answer. Humidity decrease the rate of evaporation. Temperature, wind and surface are factors that increase it’s rate.4. jun 2018.

why? When a non-volatile solute that is salt is added to a solvent that water, the vapour pressure of the resulting solution (salt solution) is less than the vapour pressure above the pure solvent (water). Thus rate of evaporation decreases.12. sep 2014.

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.16. apr 2018.

The unbalanced attraction of molecules at the surface of a liquid tends to pull the molecules back into the bulk liquid leaving the minimum number of molecules on the surface. It required energy to increase the surface area of a liquid because a larger surface area contains more molecules in the unbalanced situation.

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.25. feb 2021.

Evaporation is a unit operation that separates a liquid from solids by means of heat transfer via vaporization or boiling. The purpose of evaporation is to concentrate a solution of a nonvolatile solute (i.e., solids) and a solvent (i.e., liquid), which is typically water.

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. The surrounding gas must not be saturated with the evaporating substance. In an enclosed environment, a liquid will evaporate until the surrounding air is saturated. …24. jul 2019.

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. It is a fundamental part of the water cycle and is constantly occurring throughout nature.16. feb 2016.

The changing of a liquid into vapours or gas is called evaporation. Evaporation is used to obtain a solid substance that has dissolved in water or any other liquid. The dissolved substance is left as a solid residue when all the water has evaporated.23. okt 2020.

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. 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.
