In a liquid, the molecules are moving about. During evaporation, some molecules near the surface have enough kinetic energy to escape the bonds within the liquid.
When the liquid is heated more energy is supplied to the molecules giving them increased energy and more are able to escape the bonding in the liquid

Why is there high vapor pressure in the tropics?
Vapor pressure is just a measure of water vapor in the air. The amount of moisture air can hold increases rapidly as temperature increases, and it is very warm in the tropics. Additionally, converging air in the tropics tends to generate a lot of rain, which provides plentiful sources for evapotranspiration outside of the tropical oceans.
What happens to the relative humidity if the amount of water vapor in the stays the but the air get coolers?
The relative humidity increases, assuming that the pressure stays the same.
What determines the amount of water that can be held in the air?
The temperature determines the amount of water vapor that can be held in the air. The warmer the air, the greater the amount of water that the air can hold.
What happens to airs ability to hold water vapor as the air gets warmer?
As the air gets warmer, it's ability to hold water vapor increases.
What is humudity?
humidity is water vapor in the atmosphere that makes the weather feel hotter than it really is
Does the amount of water vapor that a volume of air can hold decrease as air temperature rises?
No. It increases. Warmer air can hold more water than colder air.
What happens to the relative humidity if the amount of water vapor in the air stays the amount but the air gets cooler?
The relative humidity increases, assuming that the pressure stays the same.
Why you see your breath on a cold day?
What you see is water vapor. The air that you exhale contains water vapor. When you exhale during a cold day, the relative humidity increases. Relative humidity is actually the percentage of the amount of water vapr in the air. (the maximum amount of water vapor that the air can hold at that temperature) The colder the air, the less water vapor it can carry. When exhaled, air mixes with cold air, the temperature of the exhaled air drops, but there is more water vapor. When the air becomes saturated, (relative humidity is 100%), the extra water vapor will condense, allowing you to see your breathe on cold days.
What is the amount of water vapor the air IS holding compared to the amount of water vapor that the air CAN hold at that temperature?
Relative humidity
What happens to relative humidity if the amount of water vapor in the air stays the same and temp increases?
The relative humidity will decrease.
Why does relative humidity decrease after the sun rises and increase after the sun sets?
"Because relative humidity is related with the temperature of the air. Relative humidity is the rate of water vapour to the maximum amount of water vapour can air hold at that temperature. The amount of water vapour that air can hold is increses as the temperature of the air increases. If the air holds same amount of water while the temperature is incresing, relative humidity of the air decreses because maximum amount of water that air can hold increases and the rate of humidity to tha maximum humidity decreses."Someone had given this answer, and it is partially correct, however, their bizarre English and grammar skills make it hard to understand. I think what they meant was that relative humidity is the amount of water vapor in the air, compared to what the air can "hold" at a given temperature. As temperature increases, the amount of water vapor or moisture the air can hold does as well.So, after the sun rises the temperature of the air increases, so does the amount of moisture the air can hold and the actual amount of water vapor in the air may stay the same, thus decreasing the relative humidity. The opposite happens at night.Relative humidity = (actual vapor density/ saturation density) x100%
What do you call the comparison of the actual amount of water vapor in the air to the amount of water vapor in the air if it were saturated?
This is called the "relative humidity."
Relative humidity changes with?
Addition of water vapor into the air, removal of water vapor in the air, decreases in temperature, and increases in temperature.
The presence of water vapor in pure air?
Increases Density
What percent does water vapor make up of atmospheric gases?
The amount of water vapor in air varies based on the temperature and density of air. The amount of water vapor ranges from a trace amount up to 4%.
How does temperature affect amount of vapor in the air?
The warmer the temperature, the more water vapor in the air. The colder the temperature, the less water vapor in the air.
Relative humidity is the ratio of the amount of water vapor in the air to?
