You will find people of all ages fond of drinking cold drinks, from children to adults. While the demand for cold drinks is high in summers, the demand does not reduce even in winters. Although many people drink cold drinks, but hardly anyone knows an interesting thing related to it and the reason behind it. Do you know why cold drink bottles are not filled completely, why empty space is left in them? If you don’t know, then let us tell you the real reason.
According to the report of Bright Side website, soft drinks, water bottles, shampoo bottles or all those things which are sold in bottles are not filled completely to the mouth, some part is left empty. You will wonder what could be the reason behind this. In fact, when bottles of such things are taken from one place to another through transport, there is a danger of their packages bursting and the lids opening, in such a situation these liquids can fall out of the bottle. But in the case of cold drinks, this is the reason, but there is another reason also.

Cold drink bottles contain carbon dioxide gas
When soft drinks are packaged, their temperature is below room temperature. That is, they are packed only after cooling them below room temperature. Then during transportation or while delivering its crate somewhere, it can be left in any kind of temperature. Sometimes the bottles are even kept in the sun. Due to this the temperature inside the bottles increases. You must be aware that soft drinks are filled with carbon dioxide gas. When a soft drink heats up, this gas starts coming out of the liquid and expands. In this way the pressure inside the bottle increases.
This is why we leave empty space
This increased pressure falls outwards. Now if the cold drink is filled till the top, there will be no extra space for the gas to expand. In such a situation, the cold drink bottle may burst and the entire liquid may flow out. To prevent this, cold drink bottles are not filled to the brim.
