Is water heated from water vapour?
Water is typically heated from a liquid state, not from water vapor. Water vapor forms when liquid water is heated to its boiling point and evaporates into the air. To heat water using water vapor, one would need to first condense the vapor back into liquid water before further heating it.
Is there water vapour in the air you breathe out?
Yes: it is one of the many waste products that your body gets rid of when you make energy through aerobic or anerobic respiration
How help of activity show that air cantain water vapour?
One simple activity to demonstrate that air contains water vapor is to take a glass filled with ice cubes and observe the condensation forming on the outside. As the cold surface cools the air around it, the water vapor in the warm air condenses into tiny droplets, illustrating that air indeed contains moisture. This phenomenon occurs because cooler air holds less water vapor than warmer air, leading to visible condensation. Thus, the presence of water droplets on the glass provides clear evidence that air contains water vapor.
How do hot air balloon stay air borne?
using hot air. Whether in a liquid or in air or a specific gas, everything has a force pushing it up that is equal to the weight of the liquid or gas that the thing displaces. For example, if you put a cube measuring one cubic foot into water, the water would exert on the cube an upward force equal to the weight of a cubic foot of water, which is 62.4 pounds for pure water. While that cube is out of the water, the air exerts an upward force on the cube equal to the weight of a cubic foot of air at sea level. To get a hot air balloon off the ground, the air inside the balloon is expanded by heating until the combined weight of the expanded air, the balloon itself, and everything hanging below it is less than the weight of the same volume of the cooler air outside the balloon.
What is a cloud?
== == Very simply, a cloud is "FOG" that is above the Earth's surface, rather than in contact with the ground.Clouds and fog are one and the same thing, very tiny droplets of condensed water vapor, so small that they do not have enough weight to fall to the Earth, and consequently they just float around in the air. IF and when enough of these droplets of condensed water vapor, collide and stick together, they become heavy enough for gravity to cause them to fall to Earth, and that is what we call rain. Other forms of precipitation occur when the vapor (or rain) is exposed to colder temperatures. === ===Clouds are formed when water vapour in the air is cooled and condenses as part of the water cycle. Clouds consist of billions of tiny water droplets (and even ice crystals) floating in the sky and appear in a variety of shapes and sizes depending on how and where they formed.I found this answer at http://www.rcn27.dial.pipex.com/cloudsrus/clouds.HTMLHope this helps.
Does the air one breathes in contain water vapour?
yes
What conditions in the air favor condensation of water?
saturated air and dewpoint temperature much lower than air temperature
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.

What is the difference between water vapour and steam?
the difference is that water vapour is just one particle that joins together with more and more to form steam
Why do clouds form when air rises?
As air rises, it cools adiabatically. This is the result of less pressure being applied to a parcel of air as it rises in altitude (as there is less air pressing down above it). As the air cools, its capacity to suspend water vapour decreases, and it may approach one hundred percent relative humidity, also known as dew point. Dew point is the temperature at which water vapour will condense in air at a given pressure. The condensed water vapour will form clouds, which may cause precipitation.
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.
How will you show that air has mass?
There are many ways to prove air has mass. One of them is : Take some water in a closed vessel and heat it till all the water boils. As we know when there is no transfer of particles mass remains constant. Therefore, the mass of the water vapour (air) is equal to the mass of the water taken. Hence, it is proved that air has mass.
Is there water vapour in the air you breathe out?
Yes: it is one of the many waste products that your body gets rid of when you make energy through aerobic or anerobic respiration
How does floating objects rise when you know that gravity pulls objects down?
Difference in specific mass per cubic deciliter, in a liquid or gas. Mind you, there is more to it. Nitrogen and oxygen have different specfic mass, yet they easily mix and do not so easealy separate. (how would we breathe air?) What's more is more to it. Heating air expands it, and when trapped (in a balloon) the average specific weight of the balloon becomes lighter than specific weight of the air outside the balloon. Given the weight per Cubic meter cubed, one can see how one tonne can be lifted. In Hot air baloons, the cloud effect plays a role too. The hot vapour of the gasburner has a LOT water vapour in it. Warm air can hold more water vapour than cold air can. Water vapour is lighter than dry air is, and the mix will rise because the mix is lighter than heated dry air. This also explains why hot air balloons can not get as high as helium balloons.
What are the conditions necessary for rusting?
The conditions necessary for rusting are water (or water vapour) and air, specifically Oxygen. If one condition is absent and the other is present then rusting would not occur but if both are present then rusting will occur
Why does moist in the mirror after you blow it?
The moist you are talking about is nothing but the water vapour that one releases, every time one exhales. As already know, when we breathe in, the air that enters gets humidified as it passes through the nasal passages. Hence, the air exhaled, or breathed out, contains considerable percentage of water vapour. Now, this water vapour exhaled out, initially is at body temperature, i.e., 37.5*C. On coming out through exhalation, the vapour soon cools down and condenses on the nearby mirror glass surface. Hence, the moist is seen.
