The primary factors that affect the potential evaporation and transpiration, if water is readily available from soil and plant surfaces, are:

• Solar Radiation and Temperature.
• Humidity and Wind.

Soil evaporation under crop canopy is affected by atmospheric, soil, and crop conditions, such as air temperature, solar radiation, soil texture, soil water content, crop type, and crop growth period.

Air in the absence of an efficient wind transport, gets saturated with evaporated moisture in the near vicinity of water surface. This reduces the rate of evaporation and eventually the total water loss due to evaporation is reduced.

The evaporation rate of a solvent depends on its vapor pressure at the processing temperature, the boiling point, specific heat, enthalpy and heat of vaporization of the solvent, the rate of heat supply, the degree of association between solvent molecules and between solvent and solute molecules, the surface tension of …

Humidity of the surroundings: The greater the humidity of the atmosphere surrounding the water, the slower the rate of evaporation. Air circulation or wind speed: The presence of a breeze or another source of air circulation directly contributes towards the rate of evaporation.

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. With the liquid, this will not evaporate.

Humidity refers to the amount of moisture or water vapour in the air. Due to high humidity the temperature of the surrounding decrease along with the rate of evaporation.

When temperature and wind speed are constant, but humidity increases, the rate of evaporation will decrease. When wind speed and humidity stay constant, and temperature increases, then the rate of evaporation will increase because warmer air can hold more water vapor than colder air.

Evaporation is a type of vaporization which occurs on the surface of the liquid. The evaporation process can occur at a temperature below the boiling point. So by evaporation only the liquid molecules on the surface get converted to the water vapour.

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 and form clouds.

Evaporation occurs at the surface exposed to the air, so increasing surface area and minimising depth of your container will increase evaporation. The fastest would be to pour the water on open level ground letting it spread out in a wide puddle only as deep as surface tension will allow.

But if you blow that humid layer of air away with a fan, replacing it with air that isn’t so saturated with recently evaporated water, the condensation rate stays low and the apparent evaporation rate increases.

⊕The rate of evaporation is directly proportional to the surface area because as the surface area increases, molecules of fluid now able to connect with air molecules on large scale.

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).

Complete step-by-step answer: i) 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.

Condensation is the change from a vapor to a condensed state (solid or liquid). Evaporation is the change of a liquid to a gas.

If we are saying that air humidity is high, then the amount of water vapour is high in air. So, now water vapour intake capacity of air is decreased. But evaporation is the process by which extra water vapour is added to the atmosphere. So, naturally with more humidity the evaporation rate decreases.

Evaporation increases with a decrease in humidity Humidity means the amount of vapor present in the air. If the temperature increases and the wind speed and humidity stay constant, then the rate of evaporation will increase since warmer air can hold more water vapor than colder air.

Temperature: As the temperature increases, the rate of evaporation also increases. Temperature and rate of evaporation are proportional to each other. Surface area: As the surface area increases, the rate of evaporation increases. The surface area and rate of evaporation are proportional to each other.

Answer. True, The rate of evaporation is directly proportional to the surface area exposed.

Relative humidity is related to the partial pressure of water vapor in the air. At 100% humidity, the partial pressure is equal to the vapor pressure, and no more water can enter the vapor phase. If the partial pressure is less than the vapor pressure, then evaporation will take place, as humidity is less than 100%.

Relative humidity greatly affects evaporation rates. When it is high, relative humidity slows evaporation; relative humidity reduces it to zero (no evaporation at all) when it reaches 100 percent.

The boiling point of water is 100 deg C at 1 atm. This is the temperature that liquid is in equilibrium with its gas phase. And you are right that below this temperature (at 1 atm) water should not vaporize.

1 seconds to evaporate, you’d need a temperature of about 14 000 degrees C. This is to vaporize the entire water droplet before it reaches the surface, via blackbody radiation, not to merely float on a cushion of water vapor.
