Question

What mkes coca cola fizz?

Answer 1

comenting on HOGHEAD answer: another possibility is a wall of UNopened cola cans slammed into by a SD70M. Hmm... I think that might be more of an explosion than people think....lol

Answer 2

Different liquids (such as water) can contain, dissolved within them, some quantity of one or many gases. In sodas, Carbon Dioxide (AKA CO2, where the 2 is properly written as a subscript) is dissolved into the liquid. The can or bottle, you will notice, is much firmer when unopened. This is because the contents of the container are under pressure greater than our atmosphere's. Typically, a liquid will absorb more of a given gas, as pressure increases, and so too as the liquid's temperature decreases.

Within the sealed, unopened container, the liquid would appear to the flat. It is only as it is opened, that the gases dissolved within the liquid escape. The lowered pressure on the liquid no longer forces as much Carbon Dioxide into the liquid, and it comes bubbling out. This is the "fizz" you notice.

Also warm soda fizzes more and goes flat sooner because the warmer liquid will not hold the same amount of Carbon Dioxide dissolved within it.

As an interesting parallel, it is oxygen gas dissolved into water that makes it possible for fish to breath under water. That is what is being achieved by that bubbling thing inside a tank. Otherwise the water would need to be replaced frequently for the fish's sake.

Answer 3

If you look on the list of ingredients, the first one is carbonated water.  This refers to the carbon dioxide gas that provides the Coke's fizz.  The answer "dry ice" is also technically correct because dry ice is frozen carbon dioxide.  Carbon dioxide is one of the few materials subject to sublimation – that is, it goes directly from a solid to a gas and back again.  Dry ice was once used to make homemade root beer.

Answer 4

club soda, i think...

Answer 5

The gas which is basically created by dry ice. If you shake a Coke enough it will run out of gas and not fizz anymore but taste different.

Answer 6

carbonation

Answer 7

Rifle 223 has got it right.  But, what possible connection does your question have to do with rail transportation (unless you've spent time imbibing cola in an Amtrak lounge car)?

Answer 8

Oxygen

Answer 9

The same thing that makes Pepsi fizz!

Answer 10

When you carry Coco Cola in train due to jerking and vibration the carbon di oxide in the drink creates the fizz.
