Evaporation and Condensation

Evaporation is an endothermic process that is the conversion of a liquid to the vapor state by the addition of latent heat. Condensation is a type of chemical reaction in which water or another simple substance is released by the combination of two or more molecules. The term is also used to describe the process by which a gas or vapor changes to a liquid. In weather, evaporation occurs when water on the earth changes to water vapor and enters the atmosphere. The opposite of evaporation, condensation transforms water vapor in the atmosphere into a liquid, often resulting in precipitation, most commonly in the form of rain or snow.

Is transpiration faster than evaporation?

My first guess would be that they evaporate at the same speed, trick question. My second guess would be that the leaves are higher, and there's much less water on the plant, so it would evaporate faster; that's not taking into account shaded areas. To me, transpiration -is- evaporation, so it's the same speed. But don't take my word for it. My first guess would be that they evaporate at the same speed, trick question. My second guess would be that the...

Why does bleach evaporate faster than water?

Bleach can be many things. In general though, solutions evaporate more slowly than pure liquids, because they have lower vapour pressures so we would not expect this to be true. ...

Graph does salt or sugar water evaporation?

Yes. The water will evaporate and leave the residue of salt or sugar. A process crystalization is also there from which solids are purified from liquids by heating and then cooling, leaving purified crystalals. ...

How much water evaporates from a pool?

Water Evaporation from a Pool The evaporation rate depends on the surface area of the pool, the temperature, and the relative humidity and the wind. I'm sure an "equation" containing the variables is known. Perhaps a civil or mechanical engineer would have a specific equation. I did find what seems to be a credible source that provides a reasonable answer. Here is the link: Marin municipal water district. They have a chart that lists 200-300 gallons per week for a medium-sized pool...

What is the difference between condensate and water?

Unless any extra particles/sediments collected on the water particles(gas), they do not differ. Condensate is just when water particles(gas), have collected on an object after evaporation, and this process runs all on water. One example is when after you take a shower, the steam, (water particles/gas), collects on a mirror and drizzles down the mirror. This ends up being water!!! ...

What is evaporation?

Evaporation is the process of liquid turning to gas by the folowing mechanism: The fastest moving molecules (those with the highest kinetic energy) at the surface of the liquid have enough energy to break the attractive bonds with other molecules. They then escape the surface of the substance. Obviously, this only occurs with the molecules at the surface of the substance. Since at higher temperatures the molecules have more kinetic energy, more of them are likely to escape, and so evaporation occurs more quickly...

Is energy absorbed during freezing?

depends on your point of view, but... it's not really absorbed in the strictest sence. by "freezing", i'm assuming you're intent is to say you are taking some substance, say water at room temperature, & then freezing it (lower it's temperature to or below the point at which the water becomes frozen). what happens to the energy is, it is transferred out of the water, to somewhere else. if using a common refrigerator/freezer, the heat energy from the water is transferred to...

Why does condensation form on a glass of iced tea?

There is always water in the air in its gaseous form. When air is warmer it can hold more water before the water begins to condense and form into droplets. That's why you hear about relative humidity in the weather report - if the relative humidity is 50% it means that there is about half the maximum amount of water in the air that it can hold at its current temperature. So the bottom line is, when air cools it can...

Can you justify a solar cover with savings from evaporation heat and chemical loss for a large commercial pool?

65% of your heat loss, especially in a large commercial pool, is through convection and evaporation. Convection is heat transfer from surface to air through wind speed and the difference between air and water temperature. Evaporation is converting water to vapor and requires a lot of energy and makes up the largest percentage of heat loss(50%).Having a pool cover, solar or otherwise, reduces convection and evaporation by approximately 90%. ...

How does evaporation from a liquid cool it down?

Heat of vaporization. It takes a lot of energy for something to change state from liquid to gas. That energy is called the heat (or "enthalpy", sometimes, if you want to be pedantic about it) of vaporization. The energy used to do this comes from taking out some of the thermal energy of the material, which causes it to cool down. ...

Are pool covers necessary for an indoor pool?

Pool covers should be put on indoor pools, because if something harmful to swim in (such as cleaning liquid) gets in the pool if it's not covered, it could ruin the pool water. No, - if you don't mind spending a good deal of money on a really good dehumidifier. If you don't use a cover your dehumifying and heating costs will run alot higher that with a cover. Usually pool rooms have alot of windows - sunlight makes chlorine dissipate faster...

Can saltwater evaporate?

Salt is dissolved in the water so when we heat it the water evaporates leaving salt below. Salt water can't evaporate. However, the water fraction of it can, and often does, but then the salt (Sodium Chloride, NaCl), is left behind. A look at the Utah salt flats shows what it looks like when it's left. This can happen when a large inland sea is then cut off from the sea, and the water is evaporated over time, leaving behind a...

How could you calculate the evaporation rate in a farm based on the humidity and temperature?

(From discussion) From a chemical engineers point of view to calculate it you would need to know the amount of rain that had fallen, the temperature changes throughout the period of evaporation. The mass of water in each kg of topsoil. the surface area of the farm. Then look into whether crops increase the rate of evaporation due to the increase in surface area. The best way to measure the evaporation would be a ground probe that tells you the soil composition...
