Evaporation occur at any temperature.
The boiling point of water is 100 oC at 760 mm Hg.
You boil a substance to evaporate the liquid.
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.
The boiling point of water at 760 mmHg is 100 oC.
surface tension of water is affected by temperature as it starts to evaporate when there is hot temperature but due to unnatural medium its surface starts to freeze when the temperature outside is cold,so this gives the reason that surface tension of water is affected by temperature.
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.
The boiling point of water is 100 oC at 760 mm Hg.
A high temperature favors evaporation.
evaporate
The water will slowly evaporate on its own at room temperature, but boiling temperature will do it much faster!
Water does not necessarily have to boil to evaporate. Evaporation can occur at any temperature, even below the boiling point of water. While boiling is a rapid form of evaporation that happens at the boiling point, evaporation can happen at a slower rate at lower temperatures.
Evaporation (not vaporization) occur at any temperature; a higher temperature increase the rate of evaporation.
It rose to 100 degrees Celsius. The water starts to evaporate?
It will evaporate at any temperature, as long as the humidity is less than 100%. It does evaporate much faster at higher temperatures though. Technically the boiling point of pure water is 100 degrees C, so that is the temperature at which it becomes gas.
The boiling point of salt is much much higher than the boiling point of water. So the salt stays behind while the temperature of the water remains at the boiling point of water.

Impurities. Impurities in water will cause the water to evaporate at a slightly higher temperature than 100 deg C. If you where to use distilled water it would evaporate at 100 deg C.
