What is the chemical formula for exhaled breath?
Exhaled breath is mainly composed of nitrogen, oxygen, carbon dioxide, and water vapor. Therefore, the general chemical formula for exhaled breath would be similar to the chemical composition of air, which is approximately N2 + O2 + CO2 + H2O.
What gas is present in exhaled?
carbon dioxide
Will water vapour decrease in amount after being exhaled by a human and before it was inhaled by a human?
exhaled water vapor will be greater than inhaled water vapor
What are the 3 ways the body excreates fluid?
The body excretes fluid through urination, sweating, and through respiration (water vapor in exhaled breath).
Why you see your breath on a cold day?
What you see is water vapor. The air that you exhale contains water vapor. When you exhale during a cold day, the relative humidity increases. Relative humidity is actually the percentage of the amount of water vapr in the air. (the maximum amount of water vapor that the air can hold at that temperature) The colder the air, the less water vapor it can carry. When exhaled, air mixes with cold air, the temperature of the exhaled air drops, but there is more water vapor. When the air becomes saturated, (relative humidity is 100%), the extra water vapor will condense, allowing you to see your breathe on cold days.
Why does your breath turn white when its cold?
The water vapor in your exhaled breath condenses- it goes from very warm to very cold. The drop in temperature makes the VERY moist exhaled breath condense into water droplets. Those water droplets are visible, just as a cloud is visible.

What is exhaled from your lungs?
Air- with a lot of carbon dioxide and water vapor.
Where does the water vapor in your breath comes from?
The water vapor in your breath comes from water contained in your body, particularly in your lungs and airways. As you exhale, this water is released into the air in the form of vapor.
Does exhaled air contain water?
Yes, exhaled air contains water vapor. When we breathe out, some of the water present in our bodies is expelled as vapor along with the carbon dioxide and other gases. The amount of water vapor in exhaled air can vary depending on factors like humidity and hydration levels.
Why does water vapor show up in exhaled air on a cold day?
When you exhale on a cold day, the warm air from your lungs meets the cold air outside, causing the moisture in your breath (primarily water vapor) to condense into tiny droplets that form a visible cloud or mist. This mist is essentially tiny water droplets that become visible in the colder temperature.
Is exhaled air neutral?
Containing carbon dioxide and water is not neutral.
