The amount of water vapor in the air varies depending on weather conditions. In extremely dry conditions there can be almost no water vapor, while in tropical areas water vapor can comprise more than 4% of the air by volume.
Saturated air at 30° C (82°F) can hold about 30 grams (1 ounce avoirdupois) of water per cubic meter of air. At 42° (108°F), the saturation point is about 55 grams, or nearly twice as much.
Water vapor varies by volume in the atmosphere from a trace to about 4%. Therefore, on average, only about 2 to 3% of the molecules in the air are water vapor molecules. The amount of water vapor in the air is small in extremely arid areas and in location where the temperatures are very low (i.e. polar regions, very cold weather). The volume of water vapor is about 4% in very warm and humid tropical air.
An average adult breathes out around 10-12 milliliters of water vapor per breath. This can vary based on factors such as breathing rate, humidity, and temperature of the air.
None. Your body maintains all water for isomerisation of fructose 5,6 in glycolysis.

How much of a cell in the human body is composed of water?
Approximately 60% of a cell in the human body is composed of water. Water is essential for various cellular functions such as transporting nutrients, removing waste, and maintaining cell structure.
How many times does the human breath compared to snake?
Humans typically breathe around 12-20 times per minute, while snakes usually breathe much slower, around 5-10 times per minute. So, humans tend to breathe more frequently than snakes.
What is is called when plants give off vapor?
Plants giving off vapor is called transpiration. This process involves the movement of water through the plant and its subsequent release into the atmosphere through small openings in the leaves called stomata.
Water makes up how much of your weight?
Approximately 60% of the human body weight is attributed to water.
Is it possible for a human to stand on water if the surface tension is just right?
No, it is not possible for a human to stand on water solely based on the surface tension. The surface tension of water is not strong enough to support the weight of a human standing. Additional factors such as buoyancy would also be required.
How much water in human breath?
i don't think humans breathe in any water but they do breath out water
What is the substance the makes a window fog up when you breathe on it?
It's the water vapor in your breath, after it becomes liquid water. Warmer air is able to hold more water vapor than cooler air. When you breathe onto a cold surface, the air in your breath is cooled, and it can't then hold as much water vapor as it did when it was warm. So some of the vapor condenses out ... becomes water instead of vapor ... and the condensed water collects on the glass. Exactly the same process is responsible when you exhale into cold air and you "see your breath".
What are fish fins used for?
Gills are organs in which carbon dioxide from the animal is exchanged for oxygen in the water.
How much water do you breathe out?
i don't think humans breathe in any water but they do breath out water
Is helium or air you breathe out denser?
Air you breathe out is denser than helium. This is because exhaled air contains a higher concentration of carbon dioxide and water vapor, which are denser than the gases in the atmosphere. Helium is much lighter than air and tends to rise up.
Why is it that you can see clouds but you can not see water vapour in the air?
Clouds are formed when water vapor condenses and gathers in the atmosphere to form visible droplets or ice crystals. These droplets are much larger and more densely packed than individual water vapor molecules typically found in the air, making them visible to the human eye. Water vapor in its gaseous state is transparent and individual molecules are too small to be seen without condensing into droplets or crystals.
How much water do we lose when we breathe?

The ratio of water vapor in a volume of air relative to how much water vapor that volume of air is capable of holding is called?
The ratio of water vapor in a volume of air relative to how much water vapor that volume of air is capable of holding is called relative humidity. It is expressed as a percentage and provides insight into how close the air is to being saturated with water vapor.
Does water vapour have mass?
Yes, water vapor does have mass. Water vapor is a gas composed of water molecules, and like all matter, it has mass. However, the mass of water vapor is much lighter compared to liquid water.
Why cant people breathe in water?
According to many scientists and researches, people cannot breathe in water because water molecules cannot be absorbed by human lungs. Humans have lungs that do not have enough surface area to absorb enough oxygen from water. Our lungs are more much more adapted to air than water.
How much water vapor do you brethe?
12 percent
Can a dolphin breathe in and out of air and water?
Dolphins are mammals. They breathe air with lungs, pretty much just like you and I. They can't breathe water. When they dive they hold their breath.
