Relative humidity expresses a percentage of humidity in the air to the maximum amount of humidity that could be in the air. For example: when the temperature rises the air will be able to hold much more humidity so the relative humidity will drop.
Humidity is actually a very bad predictor of rain except for the couple of hours leading up to a storm -- in which case you can probably just as easily see the storm clouds approaching yourself.   Humidity is associated with stormy weather conditions but it's not a good short term predictor by itself because 1) humidity frequently occurs without being followed by rain and 2) rain occurs frequently without first being preceded by humidity. What normally happens is rain causes humidity, not the other way around, but even that's not true 100% of the time (while the dew point will usually go up, if it's followed by a large warm front, relative humidity can decrease). What you probably want in order to predict rain is a barometer which measures air pressure. The faster air pressure is dropping the more likely rain is moving into your area. That combined with other indicators such as humidity (dew point) and temperature will give you a more complete picture of what kind of weather pattern you're sitting in.
Humidity levels below 30% are generally considered low. Low humidity can lead to dry skin, respiratory irritations, and dehydration. Using a humidifier or staying hydrated can help mitigate the effects of low humidity.
No. The keyword in this term is "relative." Relative humidity stands for the amount of moisture currently in the air with respect to (or relative to) the amount of moisture that can be held in the air. Colder air can hold less moisture than warm air, so there's a much greater chance of having 100% relative humidity when it's cool out than when it's warm out. For example, if you wake up on a cool morning and experience dew on the ground, it is because the cool air is holding as much moisture (i.e. humidity) as it possibly can. So you are experiencing 100% relative humidity. However, if that same amount of moisture stays in the air throughout the day, once the air warms up, the higher temperature allows for more moisture to be present in the air, and the air may not be fully saturated with moisture, thus you have a relative humidity that is less than 100%. So no, you do not have to be underwater to experience 100% relative humidity; in fact, underwater there is no air to surround you... so you're not experiencing any relative humidity at all.
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.

A device to measure relative humidity in BC times was done with a simple twig placed parallel to the ground and mounted several feet up. When relative humidity increases, the twig points down, and when it decreases, the twig points up.
Means Most of the Earth is Mostly Made Up Of That kind of Humidity . Obv.

Low, this is because the relative humidity is also lower. The relative humidity is how much water vapor is in the aircompared to how much it can hold, if it is lower, it can hols more so wet things dry faster.
The percentage of humidity represents the amount of water vapor present in the air compared to the maximum amount it could hold at that temperature. Humidity levels can vary depending on location, weather conditions, and time of day.
Temperature has a greater impact on drying than relative humidity. Higher temperatures increase the rate of evaporation, speeding up the drying process. Lower relative humidity can also help by providing a greater difference in vapor pressure, aiding in moisture removal.
Because of the humidity it is giving off when it falls onto your windshield/////the rain cools your windshield causing the humidity in your car to condense on the glass put on defroster and crack window open to clear this quickly
Water can "dissolve" in air. As the temperature and pressure of air goes up, the amount of water that can be held in the air increases. We can measure the "absolute" humidity of air, but this isn't especially useful. It is more handy to know hoe much water is IN the air, as a percentage of the amount of water the air COULD hold. That's "relative humidity". It is important because as the temperature rises, the air COULD hold more water, so the relative humidity falls. As the temperature falls, the relative humidity rises. As the air cools, when the air couldn't possibly hold any more water than it has now, the relative humidity is 100%, and we call this the "dew point", when dew will begin to settle onto the grass. If the air gets much colder, the water will condense out of the air and form FOG.
