What the difference between relative humidity and absolute humidity?
Humidity is the actual amount of moisture in a certain volume of air.Relative humidity is the percentage of the maximum amount of moisture that's possible in certain volume of air for a particular temperature.Example of Relative Humidity: Suppose a 5 ft. cube of air could could hold a maximum 10 oz. of moisture at 80 degrees. Now suppose that the cube of air actually contains 5 oz. of moisture. The Relative Humidity would be 50%.The idea of humidity refers to how much water is mixed in with the air around us. Everywhere on Earth there is always at least some water mixed in with the air; in some places, like the desert, it's just a little; in other place, like by the ocean or in a rainforest, it's a lot.The air can only carry around a limited amount of water vapor (evaporated water, or water in its gas form). At some point, there can be more water vapor than the air can hold, and the water turns into little droplets, which in nature is clouds, fog, or rain.Just "humidity," also known as "absolute humidity," means "what is the concentration of water vapor (evaporated water) in the air right now?" In other words, it would give you a measurement of how much water you would get if you could take a box of air and squeeze all the water out.This is expressed in units of mass/volume. So, for example, you could express the absolute humidity as 5 grams per liter (5 g/L) if there were 5 grams of water vapor floating around in every liter of air.Again, the air can only carry around a limited amount of water vapor. How much it can carry is determined by the atmospheric pressure and the temperature. There is a mathematical equation that lets you figure out the maximum amount of water that the air can carry based on the pressure and temperature. Relative humidity is how much water the air is actually carrying divided by how much water the air could possibly carry. People, especially weather forecasters, usually express this as a percentage. So, if the air in a particular place is carrying exactly half the amount of water that it could theoretically carry, the relative humidity would be 50%. If it were carrying all the water it could theoretically carry, the relative humidity would be 100%. The relative humidity can never be higher than 100% or lower than 0%.Relative humidity has no units, because it is just a fraction.So, ways they are alike:1. They both talk about how much water vapor is mixed with air in a particular place.Ways they are different:1. Humidity has units (mass/volume) but relative humidity is just a fraction or percentage.2. Humidity doesn't care about how much water vapor it's possible for the air to have, but relative humidity does.3. Humidity doesn't tell you anything about how close the air is to having rain or fog, but relative humidity does.Specific humidty is the amount of water in unit amount of air by weightandRelative humidity is the amount of water in unit amount of air by pressure(partial pressure)Relative humidity is one means of describing the amount of water in the air. Relative humidity describes the amount of water in the air as that precentage of the total amount air at that temperature should be able to hold.Absolute humidity describes the amount of water in the air by saying how many grams of water per milliliter of air are present.
What is the difference in temperature between 32 and 12 degrees celsius?
The two temperatures are having the same units. Can you subtract the smaller number from the larger? There in lies your answer
How can you prove hot and cold are relative term?
"Cold" and "hot" are the terms of describing temperature difference between two systems. To prove this, perform two trials in an experiment. If it is cold outside, do a trial with cold water from a faucet, spend some time outside, return to the faucet and then turn the cold water on again. Your findings will be that by changing your body's external temperature, you can feel the cold water that kept its temperature constant as relatively cold or warm. ________________________________________________________________ cold and hot are totallly relative term. it jst can be seen very much easily by a simple exp. jst take two beakers of water and in one put hot water nd in other put cold one. dip ur hands in it fr sme time n take ur hands out. you will notice dat your hand which was in hot beaker will feel cold sensation were as in other hand it will have hot sensation. here we can think the room temperature to be a critical point. so the hands being in cold beaker was having temperature lower were as in other it was viceversa.
What happen when you put water in the freezer and take it out?
It's always colder when you take it out than it was when you put it in, and if it stays in the freezer long enough, then it freezes. When the temperature of pure water drops to 32 degrees F, ice begins to form. This temperature is referred to as the freezing point. If other substances are added to the water, such as sugar or salt, the temperature must drop below 32 degrees F before ice begins to form. Some people, for example, store vodka, which contains water, in the freezer for an extended period of time without having it freeze. Read more in the related link.
Temperature below freezing means snow?
Snow does occur when temperature is below freezing because snow is just frozen rain . Lets say it rains , and the temperature is below freezing , that rain would become snow . So temperature below freezing means having snow is true .
What are two way in which air can becom saturated?
One would be the air having 100% relative humidity, meaning all the air is at the same temperature.
How do you calculate relative humidity from actual humidity?
Answeractuall humidity is given as the amount of water. use a table stating how much water the air can hold at the given temp, this is your 100% humidity. now calculate howw much you got and that would be relative humidityAnswer:To calculate relative humidity you need a wet bulb and a dry bulb thermometer and a psychrometric chart (a graph of the physical properties of moist air at a constant pressure). The chart graphically expresses how various properties relate to each other.Using an ordinary thermometer you read the dry bulb temperature(DBT). You will locate this temperature on the x-axis of the chart.Next you will determine the wet bulb temperature (WBT) from a thermometer who's bulb is covered with a wet wad of cotton and typically waved in the air until the temperature goes to its minimum. This works because dry air evaporates water and evaporation cools the wad. The temperature it reaches is related to the air's humidity. This value goes on the curved line at the top of the chart.The relative humidity (RH) is read off the chart from the intersection of the lines from these two points.
Why do doctors advice to put strips of wet cloth on the forehead of a person having high temperature.?
The evaporation of water from the cloth lowers the temperature of the cloth and thus hopefully by conduction the temperature of the person. Note that this method does not work in spaces with 100 % relative humidity.
Is 100 percent relative humidity underwater?
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.
How is heat and temperature alike?
heat and temperature is alike by having to do with how many degrees it is
What happens if the atmosphere is 100 percent saturated?
I assume you're talking about having a relative humidity of 100%, correct?Relative humidity is current amount of water vapor in the air divided by the maximum possible amount of water vapor in the air at that temperature and air pressure. If you have 100% relative humidity, water cannot evaporate.The unfortunate result of this is that sweating in warm, high humidity air (90% plus) is counterproductive - your body can do better keeping cool with the water inside of you than it can with you covered in water that will maintain the atmospheric temperature for a while even if you find somewhere cooler to recover.RH is NOT the water content of the air - if that were so, everything in the South American rainforest would have drowned long since.
