What Factors Influence the Rate of Evaporation of Water?

Hubert Galan and Zafira Smith


Our testable question because of this experiment is what factors influence the rate of evaporation of drinking water. This testable question respect different factors, such as the temperature surrounding the being evaporation, the heat range of the normal water being evaporated, the temperature of the air surrounding this inflatable water being evaporated, the moisture of the environment surrounding this being evaporated. To be able to test our question we use a bowl of water and expose the dish and the water within it, which would commence at a heat of 30 certifications celsius, to many different conditions, such as heating lamps, and lovers. In doing this we will exposing our bowl of water and water itself to the variety of different factors that we can assume can handle affecting the rate of evaporation in our drinking water, and by examining the each one of these factors we are able to determine which ones are actually influential to the rate of evaporation of this particular being analyzed.


Evaporation is when normal water changes form into gas. "Evaporation is the key pathway that normal water techniques from the liquid back into water cycle as normal water vapor, "(THIS PARTICULAR Routine: Evaporation). What this means is that gas or water vapor's main in the past into the normal water cycle is through evaporation, which ultimately shows the significance of computer. More important information on evaporation is the fact that energy is necessary for evaporation to occur. The use of energy in evaporation is that energy breaks the bonds that carry water molecules together and which will keep the water in it's liquid period. Which is why normal water easily evaporates at a high temperature, since there is enough energy or heating needed to break those bonds. Evaporation is arguably the most crucial part of the water routine. No evaporation would bring about no rainfall, no rainwater equals no drinking water for forest which provided the most essential gas for humans, oxygen. Overall without evaporation the consequences would be dangerous (Normal water and Global Change). What this shows is how important evaporation is inside our world, and that without it we won't endure. For this reason my colleague and I are trying to answer the question what factors impact the rate of evaporation of drinking water.


Water molecules are always moving, some substances are struck by other substances which cause them to gain swiftness. These molecules hitting the other person cause the vitality and the heat range to raise. Temps is the common kinetic energy of the molecules. Slower moving substances have less temperature(colder) while faster moving substances have a higher heat range (hotter). The increasing heat causes this particular molecule bonds to break, which causes water molecules to carefully turn into gas. The breaking of bonds of substances is evaporation, it entails a change of talk about, from liquid to gas. The higher the temperature, the higher the speed of evaporation. If the temperature of drinking water increases the water molecules gain more energy. Once the water substances' temperature goes up the water molecules begin to move faster and therefore evaporate faster. Basically the higher the temperature the higher the pace of evaporation (Factors Impacting the pace of Evaporation). This is the most notable factor that affects rates of evaporation. Just how we will try this is by having two bowls of water. One dish will come in contact with normal conditions, while the other bowl will come in contact with a heat light fixture. After twenty-four hours we will compare the mass of both bowls, and see if they change. After this we will conclude based on the info we received.


Wind is the natural movement of air in any given direction. In order to test the effect of breeze on the pace of evaporation of the bowl of water inside our experiment we will use a supporter and turn it onto the bowl of water being used. When evaporation occurs this vapor from our bowl will be sitting right above the surface of the water in our dish that hasn't yet been evaporated. When blowing wind is put into the environment when a body of normal water is at, the substances of normal water vapor are speedily moved off their resting position above the top of remaining normal water to the direction which the breeze is facing. This speedy removal of molecules allows for speedy evaporation that occurs since there is an elevated amount space on the top section of the remaining water which permit the water molecules to evaporate up. (HOW EXACTLY DOES Wind Affect Evaporation?) This also means that with an increased speed of blowing wind you will see an increased rate of evaporation, as the substances sitting on the top of an body of normal water will be removed and substituted and a quicker rate.


Humidity is the fact that amount of drinking water vapor in the surrounding atmosphere of the body of water, in our circumstance the cup being used in our experiment. In order to test the result that humidity has on water vapor in our experiment, we will put a lid on the the plate of water we will be using for screening. Evaporation within an airtight container escalates the amount of normal water vapor that exists in the air above the normal water in said container. When the quantity of drinking water vapor in the air above our normal water increases, there may be more wetness because humidity is the quantity of water in the surrounding atmosphere in a body of normal water. When moisture is saturated in the air, it is harder for drinking water to evaporate, because the air is filled up with water vapor. Mid-air cannot absorb an unlimited amount of drinking water molecules, and therefore there will be a slower rate of evaporation. If the area that is located above the drinking water becomes filled up with water vapor, a condensations happens to cause a balance. (Factors Influencing the speed of Evaporation). Condensation which is the opposite process of evaporation, is when normal water vapor changes to liquid, meaning that the evaporation taking place in our test would be countered by the condensation already developing to the vapor within our closed cup of normal water.


If wind influences the speed of evaporation then our drinking water will evaporate faster because wind flow increases the evaporation rate of drinking water through removing this particular vapor particles that'll be resting above the rest of our staying water( that hasn't yet been evaporated), making room for new substances to rest in the same place.

If humidity affects the pace of evaporation then our water will evaporate slower because when wetness is high, it becomes more challenging for normal water vapor molecules to type in their atmosphere, therefore giving no space for much more molecules and slowing the rate of evaporation of water.

If temperature impacts the speed of evaporation then our drinking water will evaporate faster since when water's temperatures is increased this particular substances gain more energy, which in turn causes the molecules to go faster, chance bonds faster and thus evaporate faster. *we have three hypothesis because we are trying to accurately test our questions with multiple factors in order to answer our testable question
