What is the heat of vaporization value of water?
It is approximately 539.4 calories per gram.
Does water evaporate quicker with hot or cold water?
Evaporation in water indicates a state change from liquid to gas. Water evaporates much more quickly when it is heated, because as the temperature rises the molecules move around much more quickly and eventually separate themselves from the liquid and mix with the air you breathe. The boiling point is the point where a state change occurs, similar to the freezing point. The state change at the boiling point will be from liquid to gas and the freezing point will be from liquid to solid.
What does evaporation rate mean?
Speed it up! The evaporation rate is the factor determining how fast or slow a liquid evaporates, this depends on the temperature the surface area of the liquid, the strength of air currents above the liquid, pressure above the surface of the liquid or the nature of the liquid. -Qwasas Evaporation Rate is how much of a factor(such as heat,humidity,or wind) affect the "rate" of evaporation.
Why is rain made out of water?
A real answer: Rain is water because rain is made of what evaporates into the air.Once it evaporates the stuff that isn't water does not condense into water. SO thing like gasoline change into CO2When the waqter condenses it form clouds When the clouds get large and dense enough it rainsA2. Water evaporates from the surface of the liquid, and this evaporated bit is called water vapour.This is a gas, and is invisible, and is able to rise in the air, for H2O as a molecule, weighs less than O2 or N2, the other main components of the air. Since it is a gas, diffusion also helps.As the air becomes less dense with altitude, the water vapour is even more easily able to expand and rise.Eventually, however, the air at higher altitudes becomes cold, and this will result in the water vapour condensing out as water molecules - just tiny droplets at first, quite like a fog. This we see in the sky, and know as a cloud.If the temperature drops more, then more and more of the water vapour will condense into droplets, and these will soon bump into each other and form bigger droplets. Eventually these droplets will no longer be buoyant in the air, and will fall as rain. If there is turbulence in the cloud, this will also increase the rate of droplets joining.Thus these droplets will fall down due to the force of gravity. And we feel it as rain.If the rain drops become too big (greater than c10mm) then the droplet will fall faster, and the wind of their passage will tear them apart. Raindrops much larger than 10mm are very rare.
What temperature does water condensed and turn into a gas?
This is not a cut and dry answer. The temperature that water evaporates to a gas and conversely condenses to a liquid is dependent on air pressure. Liquid boiling points can also be affected by impurities in the liquid, depending on the concentration of impurities. Thus in a pressure cooker water boils at a much higher temperature that it would under normal atmospheric pressure. This is also why you can't make a decent cup of tea on the summit of Everest because water boils at about 71 degrees Celsius at that reduced atmospheric pressure. So it is impossible to give a specific figure for this question.
How do weather and climates affect us?
The Sun's energy powers the water cycle. Temperature, air movement, and how much water vapor is in the air affect how quickly water evaporates and condenses. Because land feature affect temperature, they affect the water cycle too. When wind blows moist air up one side of a mountain, clouds form there. More precipitation falls there than on the other side of the mountain.
How much water evaporates from the seas?
28%
How much water evaporates from a cup of water in a day?
1 ounce
How much water evaporates from the pool?
This depends on many factors.

Why can we separate salt from water?
Water evaporates at a MUCH lower temperature than salt.
How much water evaporates from pool with cover on?
This depends on many factors.
How much water evaporates from a pool in the winter?
This depends on many factors.
How much heat does water release the when it evaporates?
The water heat of vaporization is 40,65 kJ/mol.
How much of the water that evaporates from a salty ocean is freshwater?
Vapors are contain practically pure water.
How much water evaporates from a pool in winter?
nearly none but most of the water might freeze.
In an activity20 grams of salt are dissolved in 70 grams of water. The water is then heated on a hot plate. When the water evaporates completelyhow much salt will be left?
If the water was pure and had no salt already mixed in it then the same 20 grams of salt would be left, as salt doesn't evaporates on the temperature at which water does evaporates.
