Exhaled air has more water vapor because it picks up moisture from the lungs and respiratory tract as it passes through. The body adds moisture to the air in the respiratory system to help keep it moist and to aid in the exchange of gases.
Inhaled air has the temperature of the surrounding environment. So in an ordinary setting, when you inhale, the air goes into your lungs and get warmed in the lungs. Hence, exhaled air s warmer. As for why there is more water vapour, think of the by-products of respiration. We inhale (diffuse into the blood capillaries of the air sacs in the lungs) oxygen and exhale carbon dioxide AND water vapour. Why is there more than inhaled air? Probably cause humidity is low.
Because you exhale carbon dioxide which has twice as many oxygen molecules which can turn into water vapor.
Approximately 4% of the air you exhale is composed of water vapor.

Which two gases are which you exhale more than inhale?
Carbon dioxide is exhaled more than it is inhaled, as it is a waste product of metabolism. Nitrogen is also exhaled more than it is inhaled because it makes up a large percentage of the air we breathe, but is not used by our bodies.
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.
Explain the amount of various gases in an inhaled and an exhaled air?
Inhaled airNitrogen: 78%Oxygen: 21%Carbon Dioxide: 0.04%Water Vapour: 0.96%Exhaled AirNitrogen: 78%Oxygen: 17%Carbon Dioxide: 4%Water Vapour: 3%
What gas is more abundant in exhaled air than inhaled air?
Carbon dioxide is more abundant in exhaled air compared to inhaled air. When we breathe in, we take in oxygen and exhale carbon dioxide, which is a waste product of our body's metabolism.
Do humans exhale more than CO2?
No, humans exhale more carbon dioxide (CO2) than any other gas. Approximately 4% of exhaled air is carbon dioxide, while the rest is mainly nitrogen, oxygen, and small amounts of other gases.
Why is exhaled air more dense than helium?
Helium is a relatively light gas which is lighter than air at ground level. Exhaled air contains a lot of water vapour and carbon dioxide relative to normal air. Since ground level air is less dense than helium, adding water vapour and carbon dioxide makes exhaled air even more heavier than helium.
What is occurring when you can see your breath on cold days?
The air that you exhale contains water vapour. When you exhale during a cold day, the relative humidity increases. Relative humidity is actually the percentage of the amount of water vapour in the air.(the maximum amount of water vapour that the air can hold at that temperature) The colder the air, the less water vapour it can carry. When exhaled, air mixes with cold air, the temperature of the exhaled air drops, but there is more water vapour. When the air becomes saturated, (relative humidity is 100%), the extra water vapour will condense, allowing you to see your breathe on cold days.
How go you know that the air exhaled by us contains water vapour?
because it condenses into water when your hot breath is exhaled onto a cold object.
Why does exhaled air saturated with water vapour?
Exhaled air is saturated with water vapor because our lungs add moisture to the air as it passes through the respiratory system. This moisture comes from the lining of the lungs and airways, as well as from water that is evaporated from the blood flowing through the lungs.
The excretory system why do you see your breath on a cold day?
The air that you exhale contains water vapour. When you exhale during a cold day, the relative humidity increases. Relative humidity is actually the percentage of the amount of water vapour in the air. (the maximum amount of water vapour that the air can hold at that temperature) The colder the air, the less water vapour it can carry. When exhaled, air mixes with cold air, the temperature of the exhaled air drops, but there is more water vapour. When the air becomes saturated, (relative humidity is 100%), the extra water vapour will condense, allowing you to see your breathe on cold days.
Will water vapour increase or decrease in exhaled air?
Water vapor will increase in exhaled air compared to inhaled air because the air we breathe in gets warmed and humidified as it passes through our respiratory system, leading to an increase in water vapor content when we exhale.
How is relative humidity affect by air temperature?
Warmer air is able to hold more water vapour than cooler air. As warm humid air cools, the water vapour condenses out as water droplets.
Which two gases are which you exhale more than inhale?
Carbon dioxide is exhaled more than it is inhaled, as it is a waste product of metabolism. Nitrogen is also exhaled more than it is inhaled because it makes up a large percentage of the air we breathe, but is not used by our bodies.
Is relatively humidity affected by temperature?
Warmer air is able to hold more water vapour than cooler air. As warm humid air cools, the water vapour condenses out as water droplets.

Why can you see clouds but not water vapour in the air?
It is because water vapour is air so it can't be seen but when we breath out in the mirror,water vapour is found.
How does water go to the air?
Water turn into a gas called water vapour. The air depending on its temperature will hold a certain amount of this. when the air comes into contact with water if the humidity of the air is such that it can hold more water vapour then the water that is touching the air will turn into the gas water vapour and become part of the air. it will do this at any temperature which explains why you can hang clothes out to drying sub zero temperatures and they dry.
