The temperature of a pan of hot water varies according to Newton's Law of Cooling: dT/dt=-k(T-A), where T is the water temperature, A is the room temperature, and k is a positive constant. If the water cools from 90°C to 85°C in 1 minute at a room temperature of 30°C, how ...
It takes 333.51 or 334 joules to evaporate 1 gram of H2O.
The needed energy at 100 oC is 48751 MJ.
A substance which is volatile does not have possess the strong intermolecular forces present in water. Water is held together by hydrogen bonding, where the positive end of one water molecule is strongly attracted to the negative end of another water molecule. This explains water's high boiling point of 100 degrees Celsius. A volatile compound will have either much less hydrogen bonding, or perhaps even the much weaker London dispersion forces as its only intermolecular force. This means less surface tension and a much lower boiling point. So it will evaporate much more quickly. Example: equal volume puddles of gasoline and water. The gasoline will evaporate much more quickly than the water puddle.
The amount of water that evaporates from a glass in a week depends on factors like temperature, humidity, and surface area exposed. Generally, a small amount could evaporate over time, but it's hard to specify an exact quantity without knowing these variables.
At higher temperatures, water will evaporate faster. So, depending on the temperature outside, it may evaporate faster, or slower, than inside.At higher temperatures, water will evaporate faster.

Mercury, with a density 13 times more than that of water, it takes a long time to boil much less evaporate.
Watering your lawn when its raining can cause too much water. Grass does not have to be constantly watered. Much like you and I, too much water can be harmful to our bodies.
The time it takes for a puddle of water to evaporate depends on various factors, such as humidity, temperature, and size of the puddle. In general, a small puddle may evaporate within a few hours to a day, while a larger puddle could take a few days or longer to completely evaporate.
This will depend on how much vinegar you are looking to have evaporate. Vinegar is a mixture of acetic acid and water. Acetic acid will evaporate faster than water at a rate of .97.
Salt does not evaporate with water because it has a much higher boiling point than water. When water evaporates, it leaves behind the salt, which remains solid. Salt can be dissolved in water, but it does not evaporate along with the water molecules.
That depends how much water, and what is the initial temperature.
This depends on many factors.
The time it takes for honey to evaporate depends on the amount, temperature, and humidity of the surroundings. On average, it can take several hours to a few days for honey to completely evaporate.
it depends on the temp.
It takes 333.51 or 334 joules to evaporate 1 gram of H2O.
cause it is constantly raining
You should water one a little everyday. If it's raining, don't water it. If it gets too much water, it will die.
