why does the foam from soda disapper faster than the foam from beer?
85697
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.

Normal soda drinks use carbon dioxide.\n\nGuinness stout uses nitrogen rather than CO2: the result is smaller bubbles, in fact it's like a creamy foam. Grab a pint and see for yourself.

I think it might take longer than over night to see a big difference in alcohol concentration but alcohol has a lower vapor pressure than water so it will vaporize faster.

I'll take a stab at this one.  \n\nIf you're comparing the two, water will disolve more NaCl than it will Sodium bicarbonate because it dissociates a lot faster and effienciently (due to its electronegativitiy and other factors).  \n\nOn that same note, if you are asking directly if both dissolve faster in cold or hot water, hot water is always your best bet with solids dissolving in water.  On another note, if you want to disolve a gas in water lower temperatures are pretty much the only way to accomplish this (but thats a different topic).  \n\nSo in short, both will disolve better in hot water!\n\nCheck out the source below it is very helpful.  Oh and by the way, Sodium bicarbonate does dissolve in water.

Their difference in polarity and density are probably the two most likely properties to affect the rate of separation. Molecular weight differences between the two liquids would probably have some impact, also temperature would effect the rate of separation.

Probably because alcohol with evaporate

Probably because the dye that colors the soap is not a compound that froths and bubbles the same way soap does, if it does at all. It also might be spread out too much as the soap expands into bubbles to be seen clearly.

They are about the same density so they sould absorb in about the same time. How you can tell this is the fact that water and milk mix completely. One does not seperate from the other (ex. oil and water)

sorry, you got it backwards.  soda water becomes less acidic when heated, as you evaporate the CO2, which IS acidic, and thus the soda water becomes LESS acidic.

Beer is saturated with dissolved carbon dioxide gas.  When the gas is released from the liquid, it causes foaming.  Anything, like salt, that can cause this CO2 to come out of the beer will cause foaming.

Soda is solution of CO2 in water under pressure.  The solubility of CO2 is highest in soft water.  When you add any thing like Ice cream or salt which are highly soluble in water it causes expulsion of CO2 (Gas) hence you observe froth.

I discussed this experiment with some of my colleagues and we think that the CO2 (carbon dioxide) causes a stirring effect which distributes the temperature more evenly in the soda. The ice cubes serve as nucleation sites for the bubbles (a place for bubbles to grow). As the bubbles grow and then release they cause the ice cubes to circulate in the liquid. This circulation causes the warmer layer below the ice to mix with the colder upper layer of soda and ice. Have you ever noticed that when you use a straw to drink a liquid that the liquid at at the bottom of the cup is warm and requires a stir to evenly distibute the cooling? The "still" beverages (water and tea have no bubbles) will have a cold layer on top next to the ice and a warmer layer on the bottom. This would cause the ice to melt slower.\n\nHere is an experiment to try. Allow some soda to get flat overnite, then try the experiment again.\n\nKeep in mind that temperature is the average kinetic energy of the particles in a substance, whereas heat is the total energy of all the particles. The air and water may have particles moving the same speeds, but the water has more heat because there are more particles. \n\nPicture it this way. The ice melts as fast moving particles slam into the slow moving ice particles. As in any collision, some of the energy is transferred to the ice particle, and with its new energy it can break out of the crystal and flow as a liquid water molecule. \n\nTo make the ice melt faster, you can use hotter (faster moving) particles to slam into it. This is why the ice melts faster on a hot day than a cold one. Alternatively, you can just use more collisions. The water is much more dense than the air, with many more particles per cubic millimeter. Thus even though the water molecules have the same kinetic energy as the air particles, there are many more of them hitting the ice each second, and the ice melts faster.

When you put an object in water--or any other fluid that is minimally compressable, like milk or oil or alcohol--the object takes up space.  Especially for fluids that are very runny--like water, in contrast to, say, old crank-case oil--the fluid will fill every nook and cranny available.  Since the water, or other non-compressable fluid, has to move out of the way for the object put in it, the apparent rise in the total volume of water-plus-object is due to the volume of the object.\n\nOf course, if the object FLOATS in water, you're in a whole new situation: the object will displace (move aside) exactly the amount of water that weighs what the object does.  That's a whole different discussion!

The gas is turned into liquid by compressing it and well mixed up with water. When we shake the soda it turns back to gas and hence needs more room than it has.

The sugar is converted to energy by the yeast, the by product is Carbon Dioxide bubble which make the dough rise (expand).  Yeast will work slower if you don't add the sugar.

Time takes to dissovle same amount of sugar(sugar cubes and powdered) in water.  \nKeep the mass and temperature of the water constant and do not stir the solution.  Since powdered sugar has more surface area, it will dissolve faster.

Soda is acidic.\nGum is rubber.\n\nI don't see why not, given enough time.\nI shall approximate the time for you...1 to 2 weeks.
