To condense is a physical or chemical change?
Condensation can be a physical process whereby a vapour becomes a liquid e.g. the 'steam' (water vapour) from your shower condenses on the bathroom window and runs down as water to form a puddle on the windowsill. Warm air can hold more water than cold air - the warm, vapour-laden air is cooled as it comes in contact with the colder glass and can hold less vapour so the surplus appears as water on the glass. In chemistry there are 'condensation reactions'
Why there is water on glass when ice melts?
because the water vapour in the air touches a cold surface such as glass and then turns back into water on the cold surface and this process is called condensation
Why do water droplets form on the outside of a glass of water?
This is called "condensation" on a glass, and "dew" if it occurs on grass / leaves. When the "dew point" of air is above the temperature of the surface of the glass, condensation will occur as humidity from the air releases heat into the glass and changes state from gas to liquid.
What is the difference between watervapor and steam?
Water vapour is water in it's gas form. It's invisible, 'dissolved' into the air. Steam is where the hot water vapour has condensed out of the air, it's a lot of small water droplets mixed in with the air.
What is the Difference between airs and gases and water vapour?
Air is the mixture of different gases (like oxigen, nitrogen, co2 e.t.c.) & water vapour. Gases are only gases, here is no water vapour. And water vapour is form after the vapourization of water at high temperature.
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.
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 would you have to do to warm moist air to make a cloud?
Cool it. The moisture in the air condenses to form a cloud when it is cooled. Eventually the moisture droplets are big enough to start to precipitate to form rain. You see your cloud of breath when you walk outside on a cold day and the moisture in your breath condenses to form a visible cloud.
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 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 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 would drophlets of water form on the outside of a glass cup?
Assuming the glass cup held a cold liquid, the air closest to the cup will be colder than the surrounding air, causing water vapour in the air to condense into liquid water droplets.
Why do the windows on a car steam up on a cold wet day?
on a wet day the air contains too much h20 in form of vapour in it. since the inside of the car is warm and outside cold, the vapour condenses on the outer side of glass to liquid form.this water on glass we observe as steaming of glass.
Why a glass of cold water perspires with water drop when exposed to air?
Condensation of water vapour in the atmosphere into water droplets on the surface. The surrounding air contains water vapour. When the air touches the glass it becomes cooler and can no longer contain so much water, so it condenses out onto the glass.
What gaseous form of water does air contain?
vapour

Is water vapour found in the air?
Yes often as the form of humidity
