These arrangements all have something in common; they are all in rows and columns. An arrangement of objects, pictures, or numbers in columns and rows is called an array. Arrays are useful representations of multiplication concepts. This array has 4 rows and 3 columns. It can also be described as a 4 by 3 array. This array has 5 rows and 4 columns.
But there are distinct differences that merit carbonated beverage packaging having its own page. For products that are not naturally carbonated such as beer, a carbonator is inserted into the process. But a carbonator works best when the fluid has cooled down nearly to the freezing point to reduce foaming during the filling process and CO2 can migrate into the product.
All beer leaves the brewer carbonated. This is accomplished in one of two ways - natural and forced carbonation. In both cases, beer and carbon dioxide are sealed in a container under pressure. The beer absorbs the CO2 giving the beer its fizz. Natural carbonation results from the fermentation process. Fermentation produces alcohol and carbon dioxide as yeast digests the sugar in the wort. Although most of the carbon dioxide is allowed to escape during fermentation the brewer will seal the beer in a container when it is almost complete. This is how natural carbonation is used to carbonate beer in holding vessels at the brewery and in casks. Anther way to use natural carbonation is in the bottle.
