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.
How could you see a bottle taken from the fridge show that there is water vapour?
clouds
Is water heated from water vapour?
NO. Water vapour is created by heating water e.g. when you heat a kettle steam floats out of the top of the kettle, that's water vapour.
Is water vapour not one of the constituents in air?
Water vapour is a constituents in air because water vapour rises in the atmosphere & is always present in the atmospere in some or the other quantity.Also 0.0001% of air consist water vapour
What forms in the sky when water vapour condense into water droplets?
these form in the sky when water vapour condenses into 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.
Is water vapor nitrogen?
No, water vapour is water. Nitrogen is around 72% of the air we breath but is not found in water, steam or vapour.
Why can you see you your breath on a cold?
your water vapour from within your body
Why has your breath got water vapour in it?
Because we create CO2+water+energy.
Why do you see breath on cold day?
The warm water vapour in your breath condenses into water droplets when it hits the cold air.
Why do you breathe in water vapour?
Because its part gas and we breath in oxygen
Do you breathe in water vapour?
Because its part gas and we breath in oxygen
Why do you have white puffs usually while breathing in cold morning?
When you breath out, you breath out some water vapour. This is normally invisible, but cold air cannot hold as much water vapour compared with warm. This causes some of the water vapour to condense in mid air in front of you, forming 'the cloud'!
Why you lost water while breating?
We lose water because we produce water vapour. For example go near a window and breath out it will start to get foggy because of the water vapour we expel.
When you breath onto a cold window and water droplet's appearit is an example of?
Condensation.... The colder temperature of the glass, causes the water vapour in your breath to condense out.
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.
What two compounds are formed when you breath up oxygen?
Carbo di-oxide & water vapour
