What did Galileo use to measure time?
i think it was a water clock
What is the main use of aneroid barometer?
The intended use of a barometer is to measure air pressure. You could also use it as a blunt instrument but that is not why it exists.
How can you prove that water vapor exists?
You can use a cold glass or metal and see the condensation. Also, you see it everyday in clouds, steam, mist/fog, etc.
Why can'y space ships use propellers to move in space?
A propeller needs a fluid in which to operate, like water or air. In space, there is not enough air for a propeller to work. Space is almost a complete vacuum.
What tool would you use to measure the distance around a pumpkin?
A cloth tape measure.
What data would be use to find out how much water vapor is in the air?
Look in the weather reports for "Relative Humidity". It is a percentage of how much water vapor is in the air compared to what the air can actually hold at a given temperature.
What weather factor is a hygrometer use for?
Hygrometers measure the relative humidity of the atmosphere. The relative humidity is the ratio between the present water vapor content of the air and the maximum amount of water vapor the air could hold at the same temperature. Cool air will not hold as much water vapor as warmer air. With the same amount of moisture in the air, an increase in temperature decreases the relative humidity, and if the temperature drops, relative humidity increases.
What is the measure of the amount of water vapor in the air?
Water Vapor in the air is measured using a sling psychrometer and the psychometric scale. Also, if you know the humidity and dry bulb temperature, you can use this scale to determine this as well. On the chart, you are looking for the numbers on the right side... Grains of Water in the air. Use the meter to get wet bulb temp, and a thermometer to get dry bulb temp. Find where they intersect and go directly right on the scale to find the grains of water. With the humidity, you will notice it goes from left to right, sweeping upwards in an arc. Find where the dry bulb temp and humidity intersect and once again go directly right to see the grains of water in the air. You can find this scale with use of Google Image Search for "psychometric scale".
Do you use hot or cold water when you put it in the vaporizer?
Well, the word vaporizer has the word vapor in it and vapor is like water vapor and in order to create water vapor you have to use heat to make it evaporate into water vapor so I suggest you use hot water.
What does it mean for the relative humidity of an air mass to be 70?
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 do electric humidifiers work?
Humidifiers release water vapor into the air to increase the overall humidity. To do this, electric humidifiers use electricity either to heat water, releasing steam, or to produce ultrasonic vibrations that produce water vapor.
How do use the word relative humidity in a sentence?
Relative humidity means the percentage of water vapor in the air compared to the total amount that could be contained. Or the measure of the amount of water vapor that air is holding compared to the amount it can hold at a specific temperature. This is different at different temperatures. Here are a couple of sentences:1. The relative humidity is 10 percent.2. We studied relative humidity in class.3. Saturation air has a relative humidity of 100 percent.
How can moist air turn into a fog?
Water vapor is transparent, but there's a limit to how much water vapor the air can hold. The proportion of water vapor in the air compared to the maximum amount of water that the air can hold is called the "relative humidity", and every weather report includes this value. But the maximum amount of water that the air can hold depends in part on temperature; the colder the air, the less water it can hold. When the relative humidity reaches 100%, you'll see the water vapor condensing into liquid water in the air. If the water droplets are small enough, we see it as fog; if the droplets are larger, it will fall as rain. So when moist air gets cold - or when cold air gets moist, as happens around rivers or damp fields - you'll see fog forming. We see the same phenomenon happens around cold objects, like a glass filled with ice. Moist air gets near the cold glass, and the water vapor in the air condenses into liquid water on the side of your glass, and runs down to make water rings on your wooden table. (That's why your mom wants you to use a coaster!)
What would happen if moisture in the air disappeared due to our increase water uses over the years?
Sorry - the more you use, the greater the amount that ends up as vapor in the air.
What are some useful gases?
We use gases every day in our lives. The gases that we use are air, natural gas, oxygen, carbon dioxide, nitrogen, and water vapor.
Does this dehumidifier work only with water, or can you use items like vapor inside?
This unit does require water,you can add vapor to the water if you wish.
