The kinetic energy of atoms (and molecules) in a system (in our case a liquid) follows a normal distribution - this is the bell shaped curve that you maybe familiar with in generating grades. It represents the number of atoms at a certain energy level: the maximum population being in the center.
This distribution is maintained as atoms are constantly trading off energy through collisions. All collisions result in the exact same total energy but the individual energies of the involved particles can vary. One atom can have its velocity elevated while the velocity of the other is depressed.
If then a certain atom has its velocity (energy) elevated into the extreme high end of the distribution tail then it has enough energy to evaporate and does so.
Now the total energy of the liquid/gas system remains the same however the energy of the isolated liquid system has gone down, energy has been removed from it. The liquid then willreadjust the distribution of the energies (velocities) of its individual atoms to reacquire the normal distribution. (NOTE: in statistical thermodynamics we say 'will' not 'must' as the quantum mechanics are allowed to. We can only say what the system as a whole will do not what individual atoms do.)
Redistributing energies to fit the normal distribution then, when there has been a net energy loss, requires the system to depress the value of the population of its maximum value - in other words the whole of the bell-curve shifts to the left - towards lower temperatures.
Evaporation of a liquid is an endothermic process.
Under vacuum conditions, the pressure is lower, which reduces the boiling point of water. This allows water to evaporate at a lower temperature than under normal atmospheric conditions. The lower pressure decreases the need for high temperatures to overcome atmospheric pressure and facilitate evaporation.
Add water (vapor) ... evaporation. Lower the temperature of the air mass.
Adding salt to water will lower the freezing point and raise the boiling point of the water, but it will not directly affect the temperature at which the water is heated or cooled.
The speed of evaporation in the water cycle is primarily influenced by temperature, humidity, air movement, and surface area of the water body. Warmer temperatures, lower humidity, increased air movement, and larger surface area of water all contribute to faster evaporation rates.
The temperature of water can impact the temperature of the air through a process called evaporation. When water is heated, it evaporates and releases water vapor into the air. This water vapor can then raise the humidity levels in the air, which can in turn affect the overall temperature. Warmer water can lead to more evaporation, increasing humidity and potentially raising the air temperature. Conversely, cooler water may result in less evaporation and lower humidity levels, which can contribute to cooler air temperatures.
Here are a few suggestions out of the many possible answers to this question. Raise the air temperature in the room Raise the humidity in the air in the room Lower the water temperature in the pool Cover the pool

Water is evaporated at any temperature but a high temperature favors evaporation.
A liquid with a high specific heat capacity, such as water, would be the most difficult to raise or lower the temperature of because it can absorb or release a large amount of heat energy for a given change in temperature. Conversely, a liquid with a low specific heat capacity would be easier to raise or lower the temperature of.
The evaporation rate of chloroform is higher than water due to its lower boiling point and higher vapor pressure. Chloroform evaporates quickly at room temperature, while water has a slower evaporation rate.
Water evaporates faster when the temperature is higher, the surface area of the water is larger, the air is dry, and if there is a strong air current. These conditions increase the rate of evaporation by providing more energy to water molecules to escape into the air.

As temperature rises, the rate of water evaporation increases.
