What two conditions in a room cause water to evaporate in two days?
high temprature and low humidity
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?
This question is ridiculous. First, on a hot frying pan a drop would evaporate in less than second. On a cold day, it might take a drop several hours, or it might freeze, then a 50 litre bucket of water would take days to evaporate in a desert, and would never evaporate in a country like Ireland. This is very silly
This effect is caused by the partial pressure of the water vapour in the air. The more humid the air, the more water vapour it contains and thus it has a higher partial pressure. This pressure tends to prevent water from evaporating. When the air is completely dry, there is no partial pressure from any water vapour and water will evaporate more quickly. The partial pressure of the water vapour plus the partial pressures of…
Water molecules can only escape at the surface. If a glass of water is left on the kitchen counter, it may take many days for it to completely evaporate. If the same amount of water is spilled on the floor, however, it may dry in an hour or so, because the surface area is much larger.Type your answer here...
because it is a process that has many steps to it and the cycle is very hard to understand, but it takes a long time --- It doesn't always evaporate slowly it depends on its' mass , position, the temperature. Its' relation to the sun it can evaporate in a matter of seconds, minutes hours, days, weeks or never appear to .
To cool down, people need to sweat, as when it evaporates it cools the body down. On dry days, it is easy to evaporate, as there is little water vapour in the air. On a humid day, it is harder for the water to evaporate as there is already too much water vapour there. As less sweat evaporates, it takes longer for you to cool down.
Your body cools itself by perspiration; droplets of sweat are excreted through the pores and onto the skin. If the air is dry, and if you have a little breeze, the perspiration will evaporate quickly. This requires that the liquid water absorb heat from the skin and surrounding air in order to be come water vapor. This cools you off. If the air is still and damp, then the perspiration remains on your skin and…
yes of course it has, because when you evaporate the solvent you will see the salt remaining under it! try it! dissolve some table salt in water, then boil it or leave it under sunlight for 3 to 4 days. if you boil it, small salt crystals are found, if you evaporate them under sunlight, big crystals are obtained. enjoy your easy experiment :P
