If the percentage in humidity is higher does it mean it is more humid or less humid?

Humidity IS water vapor in the air.
The "feel" of the humidity (dry vs hot/sweaty vs cold/clammy) is essentially the relative humidity, which is the amount of water in the air vs the maximum amount the air can hold.
So if the air is holding near the maximum it can hold, it feels humid. If the air can hold a lot more water than it currently has, it feels dry. Even if the amount of total water in the air is the same.
The absolute amount of water the air can hold is highly depended on the temperature. So on a hot day, the air can seem very dry, even though it is holding a lot of water. And at night, when the hot air cools to point where it can't hold all that water, it can get very humid, with dew and perhaps even fog as the water condenses. So the cooler air can seem humid, even though it has less water that the hot day air.

How does humidity contribute to weather?
If the area is too or less humid a plant cannot grow properly.
What happens to humidity when more water evaporates?
For water, higher humidity decreases evaporation because more water is present in the atmosphere. Less water will diffuse into the atmosphere. If it's at 100% humidity, there's no net evaporation.
Would you expect the temperature of the wet-bulb thermometer to be higher on a humid dry day?
On a dry day, water will evaporate from the wet bulb thermometer, cooling it. On a humid day, since moisture is already in the air, less will evaporate, and cool it less.
What is the difference between hot humid and cold humid air?
If it is hot humid air, the air will be filled with a lot of moisture, and your hands feel all sticky and when you breathe, the air feels thick. But when it's cold humid air, the air has less moisture and it may feel easier to breath in. But it still has the same humidity as the hot air, you just feel it different. This is because when you say the air is humid, you are basically saying that the air has moisture in it. But the air always has moisture in it, but you can feel it when there is high humidity. So when it is cold air, you feel the humidity less. Because if it is hot air, that means the sun must be out, and when the sun is out, it evaporates the sweat and moisture off your skin and goes into the air. That is why in a crowded room, we describe the air as 'stuffy' because it is filled with the body heat from all the people in the room. I hope I answered your question properly. :)
Does Higher humidity makes you sweat more?
Yes. You perspire to lose heat- from the evaporation of the sweat. In high humidity, sweat evaporates poorly, so you sweat more (because you are cooled less).
Why are there changes in humidity?
Humidity is the amount of water vapor in the air. Humidity increases when more water evaporates, and decreases when it rains or the humid air is displaced by less humid air. Generally, higher temperatures will lead to higher humidity, as more water will evaporate.
What result using a psychrometer will let you know the air has high humidity?
The relatively higher temperature on the psychrometer's thermometer, because less water can evaporate into humid air. (And evaporating water has a cooling affect on the thermometer.)
What is meant by humid specific heat?
Humidity is how much water content is in the air aroundus.I think humid specific means " as we perceive or feel it " This is why you feel hot on a humid day at 80 degree with 90 percent humidity than lets say a day that's 100 degrees with 25 percent humidity (one hundred percent humidity equals Rain) With high humidity we cannot cool off by perspiration,making us Feel warmer than it might actually be.And the reverse can of course be said the less humidity the better we can handle a very high temperature day.

How does humidity effect hydration?
The higher the humidity, the more fluid loss a person has from sweating. The more you sweat, the less hydrated you become. Excessive fluid loss from sweating without adequate oral replacement can then lead to heat exhaustion and later, heat stroke. It is necessary when out in humid conditions to make sure you are taking in more fluids than you are losing through sweating.
Why humidity is unbearable after rain?
When it's humid it makes it feel hot and sweat doesn't evaporate as fast as it does when it's less humid so you end up feeling sticky. 　 Usually if the rain cools it down enough the extra humidity isn't noticeable but if it doesn't cool everything off then all it does is make everything humid, on top of the heat that it failed to get rid of, which is just unconformable. Depends on the type of rain of course.
What happens to humidity when more water evaporates?
For water, higher humidity decreases evaporation because more water is present in the atmosphere. Less water will diffuse into the atmosphere. If it's at 100% humidity, there's no net evaporation.
What is humidity and how is it affected by temperature and pressure?
Simply humidity is percentage of moisture in atmosphere or in a gas.When temp. increases pressure reduces, that means gas percentage reduces in unit volume. But due to latent heat of water vapor expansion of vapor is less which results in increase in humidity. And when temp reduces, gaseous volume increases result in less humidity. The above case is for constant water vapor in air. If rain is there humidity increases because of chance of getting to water vapor is more.
Would you expect the temperature of the wet-bulb thermometer to be higher on a humid dry day?
On a dry day, water will evaporate from the wet bulb thermometer, cooling it. On a humid day, since moisture is already in the air, less will evaporate, and cool it less.
What is the percentage of humidity?
The short answer is the maximum percentage of humidity in the air at any temperature is 100%. The percentage of humidity or relative humidity of air is the percent of the maximum humidity or amount of water that the air can hold at any given temperature. Therefore if the relative humidity is 80 per cent at 20 degrees and then the air cools off to 18 degrees the relative humidity goes up even though the amount of humidity or water in the air stays the same. If the temperature continues to drop the relative humidity will continue to rise. Since cool air can hold less air than warm air the relative humidity will eventually reach 100%. If the temperature continues to fall the relative humidity will remain at 100% and water will come out of the air as precipitation.
