Would water evaporate at room temperatire?
Water is evaporated at any temperature.
Yes, if you place a cupful of water and a cupful of gasoline in a sunny window. Both cups have the same volume of liquid in them. 24 hours later you observe that both cups have less liquid in them, but there is less gasoline than water, why? Because gasoline, or petrol, is supposed to evaporate in room temperature, gas does not freeze but it can evaporate slower by colder temperature.
Did water did not evaporate even if the condition are kept the same WHY did the water level in the glass remain the same even if it was left for 3 days?
lets say you have a cup of water that is cold. when the air at roomtemperature hits the glass (look below) the air condenses because it is cold. this forms little drops on the outside of cup. this continues till the water is at room temperature them the water proceeds to evaporate. (When a temperature is warm molecules spread out and when they are cold they condense.)
Actually alcohol at room temperature would be of the same temperature than water at room temperature. The difference between the two is that alcohol needs less heat to evaporate. If you wet either hand in alcohol and water, the one with alcohol will feel colder because it's removing more heat from you and faster. That's basically what cold is, the absence of heat.
There are other factors to consider. Outside temperature. If you are at the artic in below zero weather the water would freeze before if evaporates. Altitude. Higher altitude on a mountain gives a lower boiling point, ant at the same temperature, would evaporate faster. Humidity. High humidity will slow the rate of evaporation. Size of the cup. A measuring cup is 8 ounces. A tea cup is less, recent cup sizes for coffee have increased…
Well... Only water can evaporate. So, the water and the water that is in the coke will evaporate at the same time, but the other substances in Coke besides water will remain put. I hope that answers your question. water the presence of sugar in coke elevates its boiling point. Actually, coke has a great deal of water in it. If you are talking about room temperature evaporation (or even evaporation by boiling as the…
Yes. If the chloroform is in a confined space, only a small fraction of it will evaporate, but if gas circulation sweeps away the chloroform vapor from contact with the liquid chloroform and there is an adequate supply of heat from the environment to maintain room temperature, eventually the entire sample will evaporate.
