Why is removing air from balloon easier than removing air from bottle?
Ballons are made of an elastic plastic while a bottle in a harder plastic
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.
What happens to a plastic bottle if air particles are removed?
If air particles are removed from a plastic bottle, the volume inside the bottle would decrease due to the absence of air pressure. The bottle may collapse or shrink in size as there is no longer any external pressure to counteract the elasticity of the bottle material.
Why does the water vapour surround the cold water bottle?
The water in the bottle is much colder than the air surrounding it, so the bottle cools the air immediately surrounding it through conduction. This causes the air to cool to its dew point, whereupon some of the moisture in the air will condense onto the bottle.
How much air in a 1.5 liter plastic bottle?
A 1.5 liter plastic bottle contains approximately 1.5 liters (1500 milliliters) of air when empty. When you fill the bottle with water, the volume of air contained within the bottle will vary depending on the amount of water you add.
Why droplets of water appears on the outer surface of the cool water bottle?
It's called condensation. The temperature difference between the bottle and the surrounding air - causes water to condense out onto the bottle's surface.
Does hot water in a plastic bottle causes it to expand?
Not necessarily. You have to have a space of air in the bottle. The expansion/contraction happens because the water is heating/cooling the air. Liquids are usually considered incompressible and hence will not change their volume when heated or cooled (unless it evaporates or melts!). Assuming that you have an air space: If you have cold water in a sealed bottle that you heat up, it will expand. If you put hot water in a bottle and seal it, it will contract as it cools. If the bottle is not sealed, there will be no volume change.
Why does a plastic bottle cave in when fozen?
The air inside shrinks its space needed.
What happens to an empty plastic bottle when you put it in the freezer?
When you put an empty plastic bottle in the freezer, the air inside the bottle will cool and contract, causing the bottle to collapse or deform. This is due to the decrease in air pressure inside the bottle as it cools down.
What things do you need to make a water rocket?
Water, an empty plastic bottle and an air pump.
How do you make a plastic bottle boat?
you get a plastic bottle
Which force stops a plastic bottle of air from being pushed under water?
Upthrust
