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.

How does increase in temperature surface area wind speed affect evaporation?
These are all variables used to calculate evaporation rate: The larger the surface area the higher the evaporation (rate) The higher the wind speed the higher the evaporation (rate) The higher the temperature the higher the evaporation (rate) The higher the relative humidity the lower the evaporation (rate)
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)
When the air temperature dcreases The rate of evaporation does what?
decreases
What does the rate of evaporation depend on?
The rate of evaporation relies on three main things. It varies according to the pressure, humidity and the atmospheric temperature.
Can wind increase the rate of evaporation?
No only the speed of light can
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.
Why does a rate of evaporation of a liquid decreases with increase in humidity?
For a given temperature and air pressure the amount of vapor that can be held in suspension is finite so as the the air becomes saturated with vapor there is less that can be added. In weather when it is raining there is very close to 100% humidity.

Why does the rate of evaporation of an aqueous solution decreases with increase in humidity?
As the humidity increases, the partial pressure of water vapor in the atmosphere (above the solution being evaporated) also increases. This results in more energy being necessary for the liquid water to evaporate, thus the higher the humidity, the longer it will take for evaporation of an aqueous solution to take place. This is essentially based on Dalton's Law of Partial Pressures.
When the temperature of the air decreases the rate of evaporation decreases?
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)
What is Effect of relative humidity on water evaporation?
humidity effects the evaporation in the following ways: 1. In a closed container rate of evaporation will have a lesser value than usual.but there will be no decrease in the rate.
When the air is cooled the evaporation rate?
a+ decreases
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)
The rate of evaporation of a liquid decreases as the temperature decreasestrue or false?
as the temperature increases, the rate of evaporation increases
Does the rate of evaporation of a liquid decreases as the temperature decrease?
Yes, the evaporation rate slows at lower temperatures.
When the air temperature dcreases The rate of evaporation does what?
decreases
Does adding sugar to water affect the rate of evaporation?
Yes, it decreases the evaporation rate. Sugar molecule contains a lot of -OH groups, which can make Hydrogen bonds with water. Since molecular attraction increases the rate of evaporation decreases.
