Plastic bottles are 'blow molded'. Basically air is forced inside a small piece of hot plastic and it expands like a balloon, except that this 'balloon' is inside a form or mold in the shape of the bottle. It is cooled and the bottle shape stays. If the softening point of the bottle is lower than the hot liquid poured in, then the plastic 'balloon' wants to shrink again.
What else can I help you with?
What plastics are in a plastic bottle?
It depends on whether the bottle is full or empty. If full, it could contain anything. If empty, it probably contains air, which is a mixture of elements....nitrogen, oxygen, argon etc
What happens if you put a glass of juice in the freezer?
Nothing. The glass gets colder. If the bottle is full of water or some other liquid it may split if the pressure of the growing ice crystals cannot be relieved by the bottles geometry or if the bottle is tightly sealed. Interestingly, if the bottle has parallel sidees and a wide mouth the pressure on the ice from the sides will melt the ice allowing it to move upwards relieving the pressure. This used to happen in days of milk delivery when milk bottle would freexe on the steps to homes, the ice would be forced out of the bottle's mouth to form a tower of milk ove the lip of the bottle.
Which force stops a plastic bottle full of air from being pushed under water?
The buoyant force exerted by the air inside the bottle is greater than the force of gravity trying to push it underwater. This buoyant force creates an upward force that prevents the bottle from sinking.
Why you cant squeeze a sealed plastic syringe that is completely full of water?
We can't squeeze a sealed plastic syringe full f water because all the space in the syringe has already been occupied by water and as a result, there is no space left to squeeze. If we attempt to do so , then the syringe will burst or crack.
Why liquids do not fill their container completely?
Because the soda has dissolved carbon dioxide at greater than atmospheric pressure, some bubbles (fizz) will inevitably escape when a bottle is opened, and if the bottle was full of liquid, it would likely spill.
Which is bigger a gallon full of liquid or a 2 liter bottle full of liquid?
A gallon is bigger
What does a 2 liter bottle of lemonade weigh?
A 2-liter bottle of lemonade typically weighs around 2.1 to 2.3 kilograms (approximately 4.6 to 5.1 pounds) when full. This weight includes the liquid and the plastic bottle. The exact weight can vary slightly depending on the specific ingredients and the bottle's material.
Can electric charges pass through a plastic bottle that is full of water with a plastic cap?
No. The plastic would keep the electric charge
How does the pitch of a bottle change?
The pitch of a bottle changes with the amount of liquid inside it. When the bottle is full, it produces a higher pitch because the liquid vibrates at a faster rate than when it is partially empty, resulting in a lower pitch.
Why is there a filled plastic bottle inside the flushing cisterns?
to close the water inlet after the cistern is full
What force stops a plastic bottle full of air from being pushed in the water?
density water's density is 1.00 g/c3 and the plastic bottle is less (plus it also has to with buoyancy)
A density bottle has a mass of 17.5g when empty. when full of water its mass is 37.5g.When full of liquid x its mass is 35g.If the density of water is1000k\cubic meters,find the density of liquid x?
defination of liquid x

Amount by which cask or bottle falls short of being full?
The shortfall in volume of liquid in a cask or bottle is often referred to as ullage. It is the difference between the actual volume of liquid and the full capacity of the container. Ullage can occur due to evaporation, leakage, or other factors during storage or transportation.
Why a sealed bottle partially filled with a liquid can float in a basin of the same liquid?
That depends on what fills the remainder of the bottle. If it is air, the average density of your bottle will be less than the density of the liquid.That depends on what fills the remainder of the bottle.

How can an egg be under water yet stay dry?
either: Put the egg in a plastic bag or hold a full water bottle over the egg
Is it a good idea to fill a bottle of water in a plastic container to the brim and leave it to freeze?
If you try to freeze water, juice or other liquids in a closed plastic container without leaving room for expansion, your container will crack or burst. I fill plastic bottles or jugs with liquid, leaving plenty of room at the top for expansion. Once the liquid is frozen, then you can safely tighten the lid and then when you want to take it off use warm water to wash it then take it off.The reason why it's a bad idea to freeze water in a sealed plastic container is because the container can break. I would say if the water bottle is full and you freeze it then burst open and then it will be an even bigger mess then if you just started with a half full bottle. Which works just as well.Leave at least a 1/4 of the plastic without water because water expands.Other notes:Jugs of ice keep the freezer from having to work as hard to cool the compartment, assuming you don't keep your freezer space full of food. In the event of a power outage the chunks of ice can help prevent the loss of your food for a little longer. It is NOT indefinite, but it does help for brief periods of time. My freezer lasted two days during a summer hurricane.There is a myth going around that freezing water in a plastic container causes the plastic to release dioxin, and thereby causes breast cancer. This is not true.
