Okay so this basically means, and this was a question in one of my earth science labs entitled "Dew Point and Relative Humidity" that the humidity levels have reached maximum capacity (100%) and can no longer support anymore water or moisture in the air.
Yes. Relative humidity is the amount of water vapor actually in the air compared to the amount that could be in the air (saturation point) at the exisiting temperature. So, if the temperature of the air changes and the amount of water vapor in it does not, the relative humidity will be different. But, if the temperature of the air changes and so does the amount of water vapor in it, then the relative humidity could be the same as before the temperature change. That is to say that the air could contain the same percentage of water vapor that it could hold at each temperature, even though the actual amounts are different.
Humidity is caused by water vapor in the air, but rain contributes to the amount of vapor in the air, so I suppose you could say they both do, but it's the water vapor that truly creates humidity.
Yes, humidity can affect air density. Moist air is less dense than dry air because water vapor molecules are lighter than nitrogen and oxygen molecules. Therefore, higher humidity levels can lead to lower air density.
Yes. The relative humidity of 100% indicates that the air is transporting all the water it can at that temperature, not that the air is 100% water. Any additional water (or drop in the temperature) would "super-saturate" the air, normally resulting in condensation or precipitation. At 35° C (95°F) at sea-level pressure, air can only carry about 40 grams of water per kilogram of air, which is only 4% by weight. So 96% of the 100% humidity air that you breathe is still air. At 20°C (68°F), the maximum concentration is only 1.5% water to 98.5% air.
It doesn't matter what the humidity is at the surface. You need to be looking up somewhere around 5-10,000 feet and up near the 700mb pressure level. You're probably not forecasting the weather though, so it would suffice to say that the air in the atmospheric column will become saturated as precipitation moves in and sublimates. By the time snow reaches the ground, relative humidity is typically 90%+ at the surface.
We often call this the saturation point or about 100% humidity.
example: say saturation level of sugar in water is 70 percent, if the solution is 70 percent sugar, it is saturated
Relative Humidity is actually measure the amount of moisture in the air. It depends on how much of the air has water in it. Let's say that the RH is 50%, that means 50% of the air has water in it.
It means it hasn't reached the point of expiration.
No. Say, "Have you reached Delhi?" You don't need the "at".
With few exceptions, if you increase the temperature of the solvent, you will increase the amount of solute that a solution will hold. So, let's say you have a saturated NaCl solution in water at room temperature. Put the beaker on a hot plate and heat it up, and it will be able to dissolve more salt. Cool it back down and it will become supersaturated (and unstable.)
Untill a balance between the liquid - let's say water - and the substance surrounding it - let's say the air - is reached. The factors influencing evaporation - when the molecules of water leave the liquid and 'fly' with the molecules of air - are the relative air humidity, pressure, temperature, (air and water movement, and so on). Water will evaporate until air humidityl allow it - that is until a moment when a full saturation of the air with the molecules of water is reached - at a given temperature and pressure! Water evaporates very slowly at room temperature, but being heated the process is intensified. Again, even at the room temperature water will evaporate when put in a vacuum - until the empty space will be filled with the molecules of water .

You could say "The humidity outside is very high."During the summer the humidity in the air is usually higher than in winter.
You should say "you could be reached on a phone no", not "you could be reached at a phone no"But the no at the end of both your phrases is also grammatically incorrect.So you should really say "you could not be reached on a phone," if I understand correctly the meaning of you phrase.
The question is a good example, but you could also say: "During a rainstorm the humidity of the air rises".
