What else can I help you with?
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.
Do you find water vapour in the air you breathe in?
Yes.
What percentage of air is water vapour?
about 4 percent
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 the air becomes saturated, (relative humidity is 100%), the extra water vapour will condense, allowing you to see your breathe on cold days.
What refers to the amount of water vapour in the air?
Relative Humidity is the measure of water vapour in air. It is the ratio of the actual water vapour in air divided by the maximum amount the water the air can hold at the existing temperature and pressure. It tells how fast or slow the water on the body or in clothes will evaporate or in otherwords is the air dry or humid. Absolute measure of water vapour in air is called specific humidity. It can be measured as ratio of mass of water and mass of dry air.
What is specific humidity and relative humidity?
Relative humidity compares the amount of water vapour present in the air with the amount of water vapour that would be present in the same air at saturation. Specific humidity is the mass of water vapour present per kg of total air.
When you breathe out on winter mornings your air is foggy?
Warmer air can carry more "dissolved" water(water wapour) than colder air can. When you breathe out moist, body-temperature air into colder air that excess water vapour condenses into tiny droplets, which create the fog that you see.
Why do scientist collect data about the amount of water vapor in the air?
Scientists collect data about the amount of water vapour in the air because if there is a lot of water vapour, they can tell you that it might be humid, or that it is going to rain, or if there is barley any, you can breathe more lightly, HOPE THAT HELPS:)
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.
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 the most common gas found in the air we breathe?
Often it is water vapour, which can vary from 0 to 4 %. Otherwise it is argon, at nearly 1%
What percentage of the air you breathe oxygen?
Around 21% of the air you breathe is oxygen.
