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.
Water vapour appears on the wall of the glass jar because the plant releases moisture through transpiration. When the jar is placed over the plant, the moisture released by the plant accumulates inside the jar and condenses on the cooler surface of the glass due to the temperature difference, forming water droplets or vapour.
Condensation put to a lower level
the main reason is condensation of water vapour in the air to water droplets
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.
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.
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.
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.
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.
Any water vapour in the air, even on a warm day, will condense on the chilled surface of the glass.
temperature of the hot water combined with that of its container is higher than the ambient temperature and when the surrounding air strikes the container, the temperature of the air increase and this increases the vapour state of the air. note, for water to form around the outside of the hot water glass, the temp of the water must be lower than the temp of the surrounding air (condensation).
3 - solid, liquid and gas (water vapour in the air above the liquid in the glass)
1. The air contains dust particles along with other gases. These dust particles stick to the window and make it appear hazy. 2. Air contains water vapour. So when the air containing water vapour gets in contact with the window, the water creates stains on the window and make it appear hazy. Thus transparent windows should be wiped regularly.
