Why does a foggy area appear on the top of a chilled bottle?
The foggy area on top of a chilled bottle is caused by condensation of water vapor in the air. When the cold surface of the bottle comes in contact with the warm, humid air, the temperature difference causes the water vapor to condense into tiny water droplets, creating the foggy effect.
How could you use a bottle taken from the fridge to show there is water vapor in the air?
Leave it on the side to warm up, and condensation will form on the inside- little water droplets. As you haven't messed with the bottle at all (ie added anything to it) it should bepure air and therefore shows there is water vapour in the air.
How does water vapor become water?
water that is a liquid, evaporates into the air. and becomes dense forming moisture (water vapor)
Where does the water vapor in your breath comes from?
The water vapor in your breath comes from water contained in your body, particularly in your lungs and airways. As you exhale, this water is released into the air in the form of vapor.
What is water that comes from the sea is?
water vapor
What water that evaporates comes from water?
Water Vapor
Why does filling a plastic bottle with cold water cause moisture on the outside of the bottleg?
The dew point is the temperature at which vapor in the air will condense and turn into liquid. The dew point is determined by the air temperature, pressure and relative humidity. Consequently, when vapor in the air comes into contact with the edge of the bottle (which, if the water is cold, is below dew point) it condenses and forms liquid on the outside of the bottle.
Where does water vapor come from?
water vapor comes from the ocean water when it goes through evaporation.
An unopened bottle of water is taken out of the refrigerator and placed on a table After a while the bottle is covered with droplets of water What phase change has occurred?
Condensation has occurred, as the water vapor in the air has cooled down upon touching the cold surface of the water bottle, leading to the water vapor turning back into liquid water and forming droplets on the bottle.
Does freezing a water bottle make the outside of it wet?
Not exactly.The water that appears on the outside of the icy bottle is condensation of the water vapor in the air around the bottle. The cold temperature of the ice in the bottle causes the condensation. There are lots of water molecules in air -- there is more water in the air on a humid day then on a hot dry day, but there is always some water in the air. When air is cooled by coming in contact with the icy bottle, it condenses, and goes from being a gas to being a liquid (just like how steam turns back into water when it cools). It is the condensed water from the air that makes the outside of the bottle wet.If a cold bottle was in air that had no water vapor in it (unlikely except in a laboratory), then it would not get wet.
Why does the vapour pressure of water contribute to the total pressure in the bottle?
The vapor pressure of water in the bottle adds to the total pressure because it represents the partial pressure of the water vapor molecules in the gaseous phase in equilibrium with the liquid water. This means that the water vapor exerts a pressure that contributes to the overall pressure inside the bottle alongside other gases present.
Why does your water bottle leave a ring of moisture on the bench?
When a cold water bottle is placed on a warmer surface, such as a bench, the air around the bottle cools down and cannot hold as much moisture, causing condensation to form on the outside of the bottle. This moisture then transfers to the bench, leaving a ring of moisture.
