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
What are the zodiac love matches?
Here is a list of the way i had always been instructed it was: (not including repeats)* Water & Water - This is the longest combination that lasts.* Water & Air* Water & Earth* Water & Fire* Earth & Earth* Earth & Air* Air & Fire* Air & Air* Fire & Fire * Also zodiac love matches are like finding your perfect soul mate. The best ones are when one sign fills in the others weakness by its strength. Like Scorpio and cancer. cancer needs protection and the Scorpio loves to take the steering wheel. He/She will protect him/her.
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.
How can you use the word Daguerreotype in a sentence?
daguerreotype is one of the earliest photographic processes, in which the image was produced on iodine-sensitized silver and developed in mercury vapour
Does the air one breathes in contain water vapour?
yes
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 conditions in the air favor condensation of water?
saturated air and dewpoint temperature much lower than air temperature
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.
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.
Which one has high vapour pressure water or alcohol?
alcohol has high vapour pressure than water at room temperature.
Which one of these is a property of air - it contracts on heating or cooling or it expands on cooling or it is made of carbon dioxide and water vapour only?
none of the above
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
Is hydrogen gas not one of the constituents in air?
There's some, but it's not a major component.
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
What is a by-product of burning hydrogen gas?
There is only one product - water. Hydrogen burns in the oxygen in air to form hydrogen oxide or water vapour. 2H2 (g) + O2 (g) = 2H20 (g)
