When you put cool water in the glass why the outside vapour appears?

as the air molecules are free to move , when we pour cold water in glass its surface become cooler than the room temperature , thr air molecules stick with the walls of glass and due to low temperature there these air molecules deposit there.

Ice water placed in a dry glass on a warm summer day will cause the water to appear on the outside of the glass.What is the process that forms water on the outside of the glass?
The process is called condensation, the ice water touching the glass causes the glass to cool and which causes the water vapour in the air to condense on the outside of the glass.
Why do you see water droplets on outer surface of glass containing ice-cold water?
This is because the air around the tumbler contains water vapour in it. When these water vapour came in contact with the cold, they contact with cold water, loses energy and converted into liquid state, which we see as water droplets.
When water droplets appears on the outside of a glass it is called?
Condensation put to a lower level
Why a glass of ice water often has water droplets which form on the outside while a hot cup of tea or soup does not?
the main reason is condensation of water vapour in the air to water droplets
When water droplets appears outside of a cold glass of iced tea this is an example of?
That's an example of condensation
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.
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 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.
If a potted plant is covered with a glass jar water vapour appear on the wall of glass jar Explain why?
Because of transpiration. Transpiration is the evaporation of cellular water (in the form of water vapour) from the stoma in the leaves of the plants.
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.
How do you convert water vapour to water?
Cool it down, for example by using a piece of cold glass
Why does the outside part of the ice cooled softdrink becomes wet on the warm day?
Any water vapour in the air, even on a warm day, will condense on the chilled surface of the glass.
