What percentage of dry air is water?
Ordinary room air will have only about 4% of water vapour in it, but this can increase quite a lot before the air feels uncomfortable.Relative Humidity is the usual measure of the amount of water vapour in the air, and can vary from a few% (normal) to over 90% (humid). At 90%, the air is NOT 90% water vapour; that figure indicates that the air contains 90% of the amount of water vapour it could contain when fully saturated.For very low percentages of water vapour in the air, (say below 1%) a useful measure and one more easily made, is to measure the dew point of the air. For this, the instrument contains a small shiny mirror that may be cooled to the point where dew just forms on the mirror surface, thus spoiling the reflection.
How can sea breeze cause rain?
The sea breeze will be carrying water vapour with it. The sea evaporates under the sun, water vapour joins the air, the sea breeze brings that water vapour inland, as the land rises (against mountains say) the air pressure increases and the water vapour condenses into clouds, and down comes the rain, into rivers, down to the sea, where it evaporates...
What does humidity MEANE?
The water in the air is called humidity, but if it's very hot outside, people will say it's humid. Humid is when there is a high level of water vapor in the air.
When you inhale air do you get a small or big amount of water vapour?
Well this depends on the humidity. Lets say the humidity is 20%. This means 20% of the air is water vapor. So approximately 20% of the air you inhale will be water vapor.
How can you say that water vapour are present in air give an activity to explain it?
One way to show that water vapor is present in the air is to cool the air. If the air temperature drops below its dew point, water vapor in the air will condense into tiny droplets, forming visible fog or mist. This process demonstrates that water vapor is a component of the air.
Why does warmer air hold more moisture in the air?
It's not really accurate to say that warm air can hold more moisture. It would be better to say that warm air provides a more conducive environment for gaseous water to be in than does cold air. The reason that water is found in a vaporous form is that the water molecules have enough energy to be in that form. If the molecules are colder (have less energy) they will be solids and liquids. Warm air transfers its energy to the solid and liquid water molecules, helping them achieve a gaseous state. Warm air -> more energy -> more energy for water molecules -> more gaseous water.
Why it is not possible to produce steam in open vessel?
Steam is produced when water vapour condenses in air. If the air in a vessel is cold enough, steam can be produced in it, open or closed. Mostly, say in a saucepan, the air above the boiling water is heated in the process of boiling, so it is too hot for the water vapour to condense in the saucepan. However, if you pour some very hot water into a cold bath (for example) you may well notice clouds of steam forming above it.
What is the meaning of humidity?
Humidity refers to the amount of water vapor present in the air. It is a measure of how much moisture the air can hold at a specific temperature, with higher humidity indicating more moisture in the air. Humidity levels can impact comfort, health, and the growth of mold and mildew.
What do you call when water vapour turns into water?
It's called condensation. ( say: kon den sashun ) or: condensating! ( say: kon, den, ssate ing )
Why does water vapour have less density than dry air?
First you must understand "density." Density is the amount of atoms in a given volume. You can artificially create situations when there are more atoms in a given volume where the atoms are either "dry air" or "water vapor." But in ordinary situations, water vapor is mixed with what we call "air" and in ordinary situations, "dry air" has less water vapor in a given volume, so, people tend to say that water vapor is "heavy" or more "dense" than "air" or "dry air."
How will you show that water vapour are present in air explain with help of diagram?
One way to show that water vapor is present in the air is by using a hygrometer, a device that measures humidity. The hygrometer will display the percentage of water vapor present in the air. You can also demonstrate this concept using a diagram by showing arrows representing water molecules in the air and indicating the percentage of water vapor present in relation to the total air molecules present.
Does ocean water have higher levels of oxygen than air?
No, air contains about 21% oxygen, while ocean water contains only about 5-10 milliliters of dissolved oxygen per liter. The higher concentration of oxygen in the air makes it easier for animals to extract the oxygen they need for respiration.
