Warm air can hold more moisture (humidity) than cool air. Therefore, when the air cools off and the amount of moisture in the air is too high, some water separates out from the air. This is why dew falls on a cool summer night or we get a frost some winter evenings.
The water bottle example is the same process, but smaller scale. The air cools off right next to the cold bottle, and cannot hold as much humidity. So, like dew on the ground, you get condensation ("sweat") on the outside of your water bottle.

The cold water in the bottle chills the walls of the bottle.
The layer of air around the outside of the bottle "shrinks" from the cold.
As it shrinks, some of it's moisture is squeezed out of it.
That moisture clings to the walls of the bottle.

Which provide more vapor in a bottle hot water or cold water?
hot
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.
How can you modify your water bottle so that it remains cold for long time?
Cover it with a thick cloth
Why does a bottle of bubble water foam more upon opening when it's at room temp?
Bubble Water (Carbonated Water) contains Carbon Dioxide gas dissolved in it. The colder the water, the more carbon dioxide the water can hold OR ... The gas, carbon dioxide is more Soluble in cold water than in warm water. When you open the bottle, you release the pressure inside of it, and the gas escapes, causing the bubbles. If the liquid in the bottle is warmer, there is more gas trying to escape, thus you get more bubbles from a warm bottle than a cold one.
What part of the water cycle causes water droplets to form on the outside of a cold water bottle?
When the water is warmer, it has a higher vapour pressure making tiny droplets of water (water vapour) more likely form in the air inside the bottle. These droplets will then condense when they make contact with the side of the bottle because it is cooler there. -Alex listin that's soo boring i mean tlk about somtin eles
What is the fastest way to melt ice in a water bottle?
submerge the bottle in cold water.
Why does hot air in a bottle collaspe in cold water?
When water is cooled, it shrinks. If the water is in a sealed bottle, it shrinks the bottle, too, collapsing it to some degree.
When a bottle is cold why does the outside get wet after you leave it for a while?
This is due to condensation. The cold surface of the bottle condenses the water vapor in the air (humidity) into liquid water.
Can hot water be used safely in a cold water bottle?
yes
Why does wrapping a bottle with a wet cloth produce a cooler bottle than placing the bottle in cold water?
It depends on the variables of temperature and humidity. Water evaporates from the wet cloth. Water needs energy (heat) to go from liquid to gas and the water gets that energy from it's immediate surroundings - in this case the cloth and the bottle - so the bottle cools. Only if the air is relatively cold and dry, of course. If it's raining, you won't get much cooling from evaporation. If the bottle is just placed in cold water it is not being cooled due to evaporation and only gets as cold as the water. If the water is flowing and cold, it may readily cool the bottle faster and colder than the wet cloth. If it's just a small bucket of water, it may not cool the bottle much.
Which provide more vapor in a bottle hot water or cold water?
hot
What kind of water bottle keeps your water cold the longest?
Stainless Steal
What happened to the bubble when you placed the bottle in cold water?
the air condenses and pulls the bottle in on itself
What happens if you put an empty water bottle in the refrigerator?
It will get cold.
Does a bottle of water freeze faster than a bottle of ice thawing?
Yes it does. Cold water freeze slower than normal or hot water.
What happens when you put cold water in a bottle on top of hot water in a bottle?
When we place a water bottle with cold water on top of a water bottle with hot water the particles in the hot water bottle rise, pushing the cool particles to the bottom. This is a type of heat transfer called convection. Basically, the hot particles in the hot water bottle rise to the cold water bottle at the top and the cool particles in the cold water bottle at the top sink to the hot water bottle at the bottom. This is one of the three heat transfers. Convection occurs in gases and liquid.
How can you cool a large bottle of hot water quickly?
pour cold water over it
