Evaporation rates are generally higher in hot, dry and windy climates. The evaporation of water is the driving force for the atmosphere's water cycle. These water droplets eventually gather to form clouds and precipitation. Coverthe pot with a lid. Think of when a physician wipes an alcohol pad on your arm before giving you an injection your arm feels cold. If you mix alcohol and water and let it sit, does the amount of alcohol in the mixture decrease? Chilling Science: Evaporative Cooling with Liquids This enables water to boil in a lower temperature and much more fluids too. This means for a given amount of time much more alcohol evaporates than water. The black color of the sheet absorbs all the frequencies of the light that helps to energize the water molecules to evaporate faster. Humidity of the surroundings: The greater the humidity of the atmosphere surrounding the water, the slower the rate of evaporation. that heat and wind do affect the evaporation of water.

Is it safe to publish research papers in cooperation with Russian academics? If air pressure is high on the surface of a body of water, then the water will not evaporate easily. Perhaps you've never seen snow. When a water molecule does this, the molecule becomes a molecule of water vapor (or steam). &=2570.0\ \mathrm{kJ\ kg^{-1}} The specific enthalpy of liquid water at this boiling point is $h_\text{liquid}=417.5\ \mathrm{kJ\ kg^{-1}}$; the specific enthalpy of steam is $h_\text{steam}=2674.9\ \mathrm{kJ\ kg^{-1}}$, which corresponds to a specific enthalpy of vaporization of $\Delta_\text{vap}h=2257.4\ \mathrm{kJ\ kg^{-1}}$. Place the water in a metal container with a good thermalcontact with its surroundings, so that it does not cool down as itevaporates. 2 What are three things that will make water evaporate more quickly? Precipitation from those clouds fills lakes, rivers, and streams with fresh water. Water evaporates faster if the temperature is higher, the air is dry, and if theres wind. But in section C, in the humid eastern U.S., normal air conditioners must be used. MathJax reference. The sun, which drives the water cycle, heats water in the oceans. The energythis phase change requires is called the latent heat ofevaporation. She or he will best know the preferred format. Cold air cant hold as much moisture as warm air. The heat from the sun makes the water molecules move faster and faster, until they move so fast they escape as a gas. In a home device, a fan draws the air through the pad causing the water in the pad to evaporate, resulting in cooler air which is then pumped through the house. Follow him on Twitter at @mattdpearce. Theoretically, if it were colder, you could actually see that., Boiling water or hot water evaporates much, much more rapidly than cold water, said Jonathan I.

TL;DR: When trying to make water evaporate quickly, it is best to spread the water over a large surface area and apply heat as evenly as possible. Much less energy is used as compared to an air conditioner. Evaporation is a key step in the water cycle. When you boil water on the stove, you get steam. Reduce the atmospheric pressure around the water by using a vacuum pump and a closed container else go into a very high altitude. When using this method, the key to quick evaporation is the temperature and velocity of the air being used. If you are not very careful to replace the lost heat energy during the evaporation, the temperature will go down.
