If you mean the condensation on the shiny surface of the bottle soon after you've filled it, then it's the cold surface cooling the air around it causing that part of the air to be able to hold less moisture vapour, and this vapour condenses out as liquid. Once the bottle has warmed to the natural air temperature this won't happen any more.

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 is a wet cloth put on the outside of a plastic bottle when filtering water?

A wet cloth on the outside of a plastic bottle can help in evaporative cooling. As the water evaporates from the cloth, it takes away heat from the bottle, which can help to keep the filtered water inside the bottle cooler, particularly in hot climates.


Why is there water on a cold water bottle?

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.


Why does a bottle inflate when a bottle-and-balloon system is placed in hot water?

When a bottle-and-balloon system is placed in hot water, the air inside the bottle expands due to an increase in temperature. Since the bottle is sealed off from the outside, the expanding air has nowhere to go, causing the balloon to inflate as a result of the increased pressure inside the bottle.


How does the water cycle work in a bottle?

If your bottle is half-full, you will see condensation forming on the inside walls of the bottle. That's because water evaporates then condensates on the outside, then falls back into the main water body. It works the exact same way as it does on the outside world here on Earth.

Does a water bottle float on top of water?

An unopened water bottle contains a small pocket of air, allowing it to float. If the water bottle were to have this air removed, its buoyancy would be determined by the purity of the water inside and outside of the plastic.


What is example of condensation?

when you take a water bottle out of the fridge, it is the water on the outside. also when there is water on your window and it is not raing.


What happens to the level of the water in the straw when the water in the bottle is cooled?

When the water in the bottle is cooled, it contracts and creates a lower pressure inside the bottle. The higher atmospheric pressure outside the bottle pushes the water up through the straw to equalize the pressure, causing the water level in the straw to rise.


Why is a wet cloth put on the outside of a plastic bottle when filtering water?

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.


How do you think the sugar got into the water outside the bottle?

The sugar likely got into the water outside the bottle through a spill or leak from the container. If the bottle was not sealed properly or if it was knocked over, the sugar could have dissolved in the water, creating a sugary solution. Additionally, if the bottle had condensation, sugar could have also been transferred through contact with the wet surface.


What part of the water cycle causes droplets to form on the outside of a cold water bottle?

it causes condensation


How do crush a bottle with ice and cold water?

As the water inside the bottle cools it uses less air pressure than the cool air outside. The results are crushing.


Why do air bubble come out of the top of a washing-up bottle when you put it in hot water?

Because the heat from the hot water is transferred through the wall of the bottle to the inside, where it heats the air, causing it to expand and come out the top of the bottle.


Is the water supposed to come out of a hamster's water bottle?

yes! if no water came out, the hamster can die


Why are there bubbles in my water bottle?

Bubbles in your water bottle are likely caused by gases dissolved in the water, such as carbon dioxide. When you open the bottle, the pressure decreases, causing the gases to come out of solution and form bubbles.
