what causes particles in a liquid to escape into a gas state?

a.)\n\nIn a liquid or a gas, not all molecules have the same kinetic energy.  Temperature is just a measure of the average kinetic energy.  There is statistical range of kinetic energies.  Those molecules that have the higher kinetic energy may escape from the liquid into the gas phase.

As the temperature of a liquid increases, the less gas it can hold dissolved. If you set a cold glass of water on the counter, it contains dissolved air. That is what th fish breath, dissolved air. As it warms less air can stay dissolved, so it comes out of solution on the side of the glass.\n\nIt is not the H or O from H2O

This is really a trick question.  The contents inside a closed (pressurized) can or bottle contains two phases.  The lower phase is a liquid solution and the upper phase is pressurized gas containing a high percentage of carbon dioxide (this is a gas solution).\n\nWhen the container is opened, the pressurized gas excapes into the atmosphere and upon doing so allows a change to take place in the solution below.  The chemical change is:\n\nH2CO3 (aq) --> H2O (l) + CO2 (g)\n\nThe gas bubbles of carbon dioxide form inside the liquid solution, turning it into a mixture (I doubt that the term mechanical has much meaning here).

The "sizzle" that you hear comes from the fact that you are boiling the water rapidly.  Since the Boltzmann distribution predicts that there is an array of energies available in the system, i.e. molecules in a droplet in this case, molecules will absorb differing amounts of energy to be converted into a gas and will therefore be expelled at different rates.  The different velocities of the gas produced create a white noise (sound produced over a spectrum of frequency) that you hear.  I don't know if this is entirely accurate, but it sounds good.

As the temperature of a liquid increases the particles have more kinetic energy and can move more freely so an object passing through the liquid will experience less friction.

molecules slowly dissipate into the air. Some molecules faster than others depending on how concentrated they are and if they are in a liquid state

Because gases don't "dissolve", such as sugar into water; or become "micible" in a liquid. For example if your try and mix cooking oil with water they won't mix. This is because in each layer all of the water molceules are up against one another, and like wise with the oil molecules. \n\nNow since gas molecules (or atoms) are not up against one another, but are seperated by a small distance. Since there is open space, another gas can occuply that space and does not need to "dissolve" into a gas. \n\nWhen you reach a point where their is no space, the gas then turns into a liquid and then solubility will come into play. Under hihg pressure you may know that natural gas is sotred as a liquid (in the tank is under pressure), and when it leaves your stove it comes out as a gas.\n\nHope i didn't confuse you

Well. Okay its like this. Most times a chemical in a can is gas, but while its in the can its liquid. This is because of pressure. It pressurizes it to a point of where it would be if it were really cold. When something that is a gas at room temperature is cold, say below freezing, it would be liquid. When its compressed to a liqid state it is going to be cold. I hope this makes sense. Instant message me if it doesnt and ill explain more.

you're forcing the CO2 out of solution all at once.  because it can only exit through a small opening it seems explosive

When a gas is heated the electrons present within the gas atom jump to a higher energy state and become unstable. The energy variation between them make the atoms much more intolerant towards each other, hence the atoms occupy greater distance between them to maintain stability at that temperature.

Cold liquids dissolve gases better than warm ones. When you heat the bottle the temp. of the drink drops and the dissolved gases escape. But stay inside the bottle. Further heating cuaseas them to expand resulting in greater kinetic energy of molecules resulting in the bursting of the botle.

It's a colloid in the form of gas in a solid.

sanjana,\n                diffusion is natural mixing of particle .if u have reddish brown bromine gas in test tube with another test tube above the gas u will find that the red colouration of bromine gas will soon spread to the test tube on the top.in same way if liquid ink is left in bottom of teat tube full of water it will spread evenly throughout the water.a solid crystal of pottasium manganate if left in water will also naturally spread throughout by diffusion,but its colour spread more slower than gases or liquids.diffusion can only take place if matter is made of particles.if matter had been coninuous there would not have been enough space for liquid and solid to mix together.\ndiffusion take place much more quicker w gases than w liquids or solids.evidence for this is way smells travel.gases r generally lighter than liquids and solids therfore their particles move more quickly.in fact rate of diffusion is inversly related to mass of particle.therefore a dense gas like carbon dioxide with heavy molecules diffuse more slowy than lighter gas hydrogen\ndo u know why i have written\nbecause i am ur neighbour\nfrom pakistan\nif u need my help,plz contact through im or email\nfor web resources\nsearch at google and wikipedia\nali\npakistan

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.

The gas molecules in the container get ionized

The freezing point drops, by the Clapeyron equation. See the attached reference for details. \n\nThe answer above is dealing with ideal gases, not liquid water.

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!
