What is the general term for water vapor in the air?
humidity
What does it mean for the relative humidity of an air mass to be 70 percent?
Let's do a quick review of some facts about water vapor in air, and then we'll tackle this question. An air mass will have a given temperature and a given pressure. For air of a given temperature and pressure, only a certain amount of water vapor can be "suspended" in that air before it begins to condense and precipitate out (as rain, snow or something else). When the amount of water vapor in the air is at it maximum (for whatever temperature and pressure we cite), that air has 100% of the water vapor in it that it can hold. Any more water vapor and water will condense and precipitate out, as we stated. That's all we need to know to take on this question.When we consider the amount of water vapor in a given air mass, we use a "standard" or and "index" to relate that amount of water vapor to something "fixed" to make our measurement. The reference in this case will be the maximum amount of water vapor that an air mass can hold at that temperature and pressure (whatever they are). In the case of this question, if the relative humidity of an air mass is 70%, that air mass (whatever its temperature and pressure) is holding 70% of the water vapor that it can possibly hold. Note that term we use is relative humidity. The "amount" of humidity in an air mass that has a relative humidity of 70% is 7/10ths (70%) of the amount of water vapor that it can possibly hold altogether. We've compared the amount of water vapor in the air to the maximum amount of vapor that it can hold.While it is true that an air mass may have this or that temperature and pressure, in any given air mass of whatever temperature and pressure, there is some maximum amount of water vapor that it can hold, and when we look at the amount of water vapor in that air mass, we compare it to that maximum amount that it can hold. That's relatively humidity, and when relative humidity reaches 100%, that air is saturated with water vapor and we can expect it to begin to precipitate out in the form of rain or another form of precipitation (depending on temperature and conditions aloft).It might help to note that warmer air and air at higher pressure can hold relatively more water vapor that cooler, less "pressurized" (less dense) air. But whatever the temperature and pressure of an air mass, there is some maximum amount of water vapor that it can hold, and we look at how much is in it, and compare that to the maximum amount, and call the comparison the relative humidity.
How does temperature affect humidity?
Temperature does have a direct effect on relative humidity. ( just to make the water vapor move faster when war and slower when cool). As temperature goes up, the ability of the air to hold more gas goes up, so relative humidity goes down (unless more water vapor is being added). very good answer if you don't trust it. i got an A on a take home test with this answer Temperature affects humidity when they take place in the Dew point when water vapour changes to liquid. At this temperature humidity is high. The higher the temp, the more water vapor can be carried in air. Thus if you heat air (as is done in the winter) the relative humidity drops ... the air seems dryer even though the total amount of water vapor is unchanged.
What is an oodle?
An oodle is a large amount of something. See: Units of measurement. Eg: "Oodles and oodles of noodles."
What does the word mass mean in science term?
The word mass in science means the density of an object.
What is the amount of water in the atmosphere?
The amount of water vapor in the atmosphere varies from place to place. Humidity is the term used to describe the amount of water vapor in the atmosphere.
The amount of water vapor in the atmosphere is known as what term?
Humidity
What term represents the amount of water vapor in the air?
humidity
What is humudity?
humidity is water vapor in the atmosphere that makes the weather feel hotter than it really is
What term is given to the amount of moisture in the air?
The amount of moister in the air is called the relative humidity. It is the ratio of the partial pressure of water vapor in an air water mixture to the saturated vapor pressure of water.
What do you mean the term humidity?
Humidity is the amount of water vapor in the air.Humidity indicates the likelihood of precipitation, dew, or fog.
What is the term for water in the atmosphere?
Water vapor
What is the term for gaseous water in the atmosphere?
Water vapor
What is the meaning of humidity?
Humid refers to the amount of moisture in the air. When you say the air is humid it is when there is a lot of water vapor in the air. When there is little water vapor in the air it is usually referred to as low humidity or dry air. There is no exact amount of water vapor in the air that determines whether we say it is humid or not.
What makes up term hydrosphere?
The prefix hydro- means water, so it simply means all the water in our environment, from the oceans, lakes, and rivers, to the water vapor in our atmosphere, to the water underground in aquifers.
What term is givenn to water that is a gas?
It is called steam or water vapor.
What is the term for the change of water from ice to a vapor?
Sublimation
