Why Carbonated soft drinks make a whoosh sound when the bottle or can is opened?

because the co2 is pressurized, meaning the molecules have greater kinetic energy even at the same temperature. when the seal is broken, it depressurizes so the kinetic energy of the molecules can equalize, and so lots of co2 molecules rush out, making a whoosh sound because they cause air molecules to vibrate as they move, making sound.

I'm really not sure but it seems as though a glass of soda with ice covers it...the gas is in the carbonation; the liquid is of course the soda itself, and the ice is the solid?

Pepsi is carbonated (contains bubbles of carbon dioxide).  This means that there is actually less volume of frozen liquid to be melted.

exactly the same question was asked on brainiac, i was able to see it and it doesnt do anything tapping a soda can is useless\n\nhttp://www.g4tv.com/brainiac/episodes/4816/Episode_21_What_is_Faster.html\n\nhere a few links with tests of that question\nhttp://www.nerdygirl.com/sodascience.php\n\nquote : Based on the data we've collected (see Table 1), it seems certain that tapping has virtually no effect on the amount of foam one can expect from a soda can. The data in the Table 1 supports this -- you will notice, actually, that there is frequently more foam in the tapped cans than in the untapped cans.\nhttp://www.stevespanglerscience.com/experiment/00000024\nquote: Most people have learned to tap the top of the can before opening it. Scientifically speaking, THIS DOES NOTHING! However, tapping the side of the can knocks bubbles off the bottom and sides of the can, at which point they rise to the top. The trick is to dislodge the bubbles from the sidewalls and bottom of the can so they can float to the top of the can (because gas is lighter than liquid) and there is only a small amount of liquid blocking their escape when you open the can. Remember, SNAP the SIDE instead of tapping the top.\n\nas you can see it is scientifically proved that it is uselles :-)\n\nhttp://www.newton.dep.anl.gov/askasci/gen01/gen01124.htm\nmore proof\nand you will find even more if you search for : tapping soda can\nhope you like this answer\n\n:-)

lol thats a funny question i think the reason they make those noises is because there are air pockets in them and when the air pocket bust it goes snap crackle pop lol

There are several factors in your gastrointestinal system that make it do those noises.\nFirst, it is in constant movement due that it has its own nervous system which keeps it in movement so that all the nutrients can go through the system and can be absorbed at different points of your intestines; and there are a lot of hormones that help with this movement too, but they are activated in a more cyclic pattern according to when you had your last meal.\nInside the gastrointestinal system there are a lot of things that make funny noises when they are moved, all the food is in liquid form because the stomach used its acid and its movements to disolve and crush everything you ate, and in your small and large intestines there are billions of bacteria that produce gas; when you move liquids they make noise and if you mix gas and liquids you get bubbles that when pop make noise too.\nSo in conclusion the noise comes from the constant moving of the contents of your gastrointestinal system led by the nervous and endocrine system.

You have sensitive teeth and the compounds in the beverage activate the pain receptors.  It is has some thing to do with the electrolytes in the brew

The fizz is a bunch of bubbles but they dont "explode" because of the static electricity in the hand. When the soda is made, you basically have a shit-load of carbonic acid in it. Carbonic acid is a fairly unstable substace. If you give it any reason, it will conver to carbon dioxide and water. so to keep it the carbonic acid form, the producers put a lot of preassure in the can. As soon as the can is opened a lot of the carbonic acid gets turned into carbon dioxide because you get rid of this preassure. This is evedent becasue you see the bubbles being formed when opening pop. All of the acid is not turned into CO2 though. Some of it get transformed due to the heat in the mouth (this is your fizz). if you stick a finger while pouring the drink, you are heating the pop thus creating the carbondioxide before it actually reaches your mouth. As a result you get to feel less amount of the fizz.

Too much caffeine will make you jittery, too much carbonation will give you lots a bodily noises, but the worst part is all the sugar it contains. If soda isn't used in moderation, the pounds will add on. Not to mention, it's horrible for your teeth.

At atmospheric pressure there is very little carbon dioxide in the air and an open container of beverage will have almost nil CO2.  If the beverage is placed in a can and subjected to high pressure CO2, far more CO2 will be disolved into the beverage.  When you open the can the beverage holds far more CO2 than it should in free air and the excess tries to escape.  The CO2 slowly comes out of solution by nucleating, for example on the inner walls of the can and forming bubbles that rise to the surface.  These bubbles have very poor films (unlike soap bubbles) and pop making fizz.\n\nInterestingly, if you shake a closed can of carbonated soda, the pressure inside the can will not increase even though the soda will nearly explode when you open the can.  Shaking the can allows the free CO2 in the can to thoroughly mix with the soda providing almost unlimited nucleation points for the CO2 to form bubbles and escape (all at once!)

Soda is carbonated.  That means they forced a gas (carbon dioxide) to become soluable in the liquid.  The gas is dissolved in the liquid; it just took a lot of pressure for it to happen at the soda plant.  This is a purely physical relationship, nothing chemical about it.  You can displace this gas by various means.  Heating the soda helps the gas to come out of solution.  You can shake the soda, to help dislodge the gas molecules.  Finally, by adding something else that can dissolve in the liquid you will force the gas molecules out of the liquid.  I think it should work with other dissovable substances.

well, when they make the soda, they inject carbon dioxide (the gas you exhale as a waste-product of respiration) at a pressure of several atmospheres (atmospheres are just a way of measuring pressure, the earth exerts a pressure of 1 atmosphere at sea-level, less pressure above sea-level, and more below it).  So the CO2 (carbon-dioxide) is injected at a pressure several times greater than normal.  CO2 easily dissolves into most liquids at normal atmospheric pressure, but even more so at greater pressures, therefor allowing larger volumes of gas to be dissolved into said liquid (it also dissolves more easily into colder liquids, which is why cold soda has more "fizz" than warmer ones).  Now that the CO2 is in solution, the container is sealed, so the atmospheric pressure is higher than that outside of the container.  When the container is opened, the pressure is equalized, and these large volumes of CO2 come out of solution, forming small bubbles, releasing the CO2 into the air, as the increased atmospheric pressure is no longer present to keep the CO2 in solution.  Now when you drink it, these small bubbles of CO2 hit your tongue, and the actual "taste" of the fizz, is actually a mild burning sensation caused by carbonic acid.  And that is why soda pop fizzes.  On a related side-note, this is in essence what happens to scuba divers who experience decompression sickness, or "the bends".  Gases which are constantly present in our bodies (in this case we are concerned with the nitrogen that is present), exhibit similar properties to CO2.  As the diver descends, he is increased to increasing pressure, much more so than elevation changes on land, since water is many times heavier and denser than air.  As the pressure increases, more and more nitrogen is absorbed and put into solution in the diver's body tissues.  When it comes time for the diver to ascend to the surface, he must do so slowly, if he does not, the effect is similar to what happens when you open a soda.  If he ascends at a normal pace, the nitrogen is easily released, but if he ascends to quickly, the sudden change in pressure causes the nitrogen to be released very rapidly, therefor forming small nitrogen bubbles in the various body tissues.  In effect, he has been opened like a can of soda.  These bubbles can form in any tissue, leading to extreme pain, deformity (if enough bubbles are formed in the bones), paralysis (if enough bubbles are formed in the spinal column or other major nerve clusters), or even death (if enough bubbles form in the brain).  I hope this answers your questions!

Trying drinking a carbonated beverage. Everytime I drink Rootbeer it causes me to belch.

Hey.. if you throw a can of soda, does it explode?

Beer foam is related to it's protein content.  soda had no protein so it doesn't foam at all.  there are also antifoam compounds that can be added to solutions with high protein to reduce the amount of foaming that occurs.
