Because (in simple terms) there is more water, in vapour form, in the air so it is harder for even more to evaporate compaired to when there is no vapour - humidity - in the air.

Does higher humidity increase the rate of evaporation?

Yes, higher humidity decreases the rate of evaporation. This is because the air is already saturated with moisture, so it can't hold much more water vapor. This means that evaporation occurs at a slower rate in high humidity conditions.


What things have a effect on evaporation?

Factors that can influence the rate of evaporation include temperature (warmer temperatures increase evaporation), humidity (lower humidity increases evaporation), air movement (wind can enhance evaporation), surface area (larger surface areas increase evaporation), and the presence of solutes (decreases evaporation).


When air is cooled the evaporation rate called?

When air is cooled, the rate of evaporation decreases. Cool air has less capacity to hold moisture, which results in a slower evaporation rate. As the temperature decreases, the relative humidity of the air increases and the rate of evaporation slows down.


What are 3 factors that influence evaporation?

Three factors that influence evaporation are temperature (higher temperatures increase evaporation rate), humidity (lower humidity levels increase evaporation rate), and surface area (larger surface areas lead to higher evaporation rates).


What things affect the rate or speed of evaporation?

Factors that affect the rate of evaporation include temperature (higher temperatures increase evaporation), humidity (lower humidity levels increase evaporation), surface area (larger surface areas lead to faster evaporation), and airflow (increased airflow can enhance evaporation).


What is the conclusion on the rate of evaporation?

The rate of evaporation depends on factors like temperature, humidity, surface area, and airflow. Generally, warmer temperatures, lower humidity, higher surface area, and increased airflow can increase the rate of evaporation.


What happens when the rate of evaporation of a liquid as the liquid is cooled?

Rate of evaporation depends on temperature. As Temp decreases, so does the rate of evaporation.


What are the factors effecting evaporation?

Factors affecting evaporation include temperature (higher temperatures increase evaporation), humidity (lower humidity increases evaporation), surface area exposed to air, and wind speed (increased wind speed can enhance evaporation). Additionally, the presence of impurities in the liquid can also affect the rate of evaporation.


What factors influence the rate of evaporation in a given environment?

The rate of evaporation in a given environment is influenced by factors such as temperature, humidity, surface area, and air movement. Higher temperatures, lower humidity, larger surface areas, and increased air movement all tend to increase the rate of evaporation.


Three factors that effect the rate of evaporation?

Three factors that affect the rate of evaporation are temperature (higher temperature increases evaporation rate), humidity (lower humidity increases evaporation rate), and surface area (larger surface area increases evaporation rate).


How does humidity effect the rate of vaporization of a liquid?

Higher humidity decreases the rate of vaporization of a liquid. This is because when the air is already saturated with moisture, it reduces the evaporation rate of the liquid by creating a barrier for vapor molecules to escape into the air.


When the temperature of the air decreases the rate of evaporation?

Air is already in evaporated state(gas) . however the rate of evaporation decreases in the sense its volume decreases(less space is occupied by the molecules)
