EVAPORATION is the process by which liquid water enters a gaseous state as water vapor. This can occur at any temperature above the freezing point of 32°F / 0°C. Evaporation occurs at the surface of a liquid as kinetic energy from some molecules is transferred to others, which can then escape into a gaseous medium (such as air). Adding any heat to liquid water will speed up molecular motion and increase the rate of evaporation. The molecules which remain in the liquid will have lost kinetic energy and therefore exist at a lower temperature. This is called evaporative cooling, and is evidenced when a damp cloth is rapidly waved in the air, the lost energy cooling whatever liquid is left behind in the cloth. At the BOILING POINT of water, heated water changes phase (normally below the surface or where the heat is being applied) and bubbles upward as steam until it reaches the surface and escapes as vapor. Below the freezing point of water, ice entering the air directly as vapor is called SUBLIMATION. (More easily visible with frozen carbon dioxide, or "dry ice", which is never liquid at normal room pressure. It goes from solid to gas at -109°F / -78.5° C )

∙ 6y agoWhen water molecules at the surface gain sufficient energy they can escape in the atmosphere. Molecules are in permanent movement at any temperature.
Evaporation (not vaporization) occur at any temperature; a higher temperature increase the rate of evaporation. The energy of water molecules increase by a temperature increase and some molecules at the surface can escape in the atmosphere.

Why does room temp water evaporate good?
Evaporation occur at any temperature.
Is it possible for a cup of water to completely evaporate in the room with the constant temperature?
Yes, it is possible.
Why doesn't water evaporate in room temperature?
water boils at 100o C.but room temperature may not rise to that much. only after boiling it may be converted to the gaseous state.
Where does water evaporate more quickly?
The best condition for water to evaporate is in a temperate controlled room at 74 degreesFahrenheit. also add a sunroof and proper air ventilation
How fast does water in a above ground pool evaporate at 80 degrees in a week?
A formula doesn't exist; this depends on the temperature, pressure, room volume, amount of water, etc.
Why does room temp water evaporate good?
Evaporation occur at any temperature.
What temperature is needed to separate magnesium chloride from water?
The water will slowly evaporate on its own at room temperature, but boiling temperature will do it much faster!
Is it possible for a cup of water to completely evaporate in the room with the constant temperature?
Yes, it is possible.
How much time it will take to evaporate water in room temperature exact time?
A formula doesn't exist; this depends on the temperature, pressure, room volume, amount of water, etc.
Why doesn't water evaporate in room temperature?
water boils at 100o C.but room temperature may not rise to that much. only after boiling it may be converted to the gaseous state.
Will dry ice evaporate at room temperature?
Yes, dry ice will evaporate at room temperature. Carbon dioxide, the constituent component of dry ice, is a gas at room temperature.
How long does it take to evaporate 1liter of water at room temperature with an area of 20cm²?
it depents on the environment
What is the temperature when boiling water starts to evaporate?
There is no such temperature to start evaporating. Even in the room temperature or in a refrigerator, water does evaporate. When a particular water molecule absorbs adequate energy (let's say from heat), there will be a phasechange in that molecule from liquid to gas, and it's called evaporation.
How much time would 5ml of water take to evaporate under room temperature?
This depends on many factors.
How much heat is required to evaporate a gram of liquid water at room termperature?
First, the water must be raised to a temperature of 100 degrees - this requires 4.181 joule/(degree x gram). For example, if your "room temperature" is 20 degrees, multiply that by 8. Then you have to actually evaporate it - that costs 2260 joules/gram.
Could Apple juice evaporate at room temperature?
yes
Does water evaporate faster in sun or in the dark?
Water evaporate faster in sun because the temperature is higher.
