What is the name given to a liquid changing into a gas??

Evaporation is one of the two forms of vaporization. It is the process whereby atoms or molecules in a liquid state (or solid state if the substance sublimes) gain sufficient energy to enter the gaseous state. It is the opposite process of condensation.

it's the breakdown of food that creates gas. alka seltzer or bicarbonate is recommended.

When a controlled strem of air is passed over hot coke, "coke gas" or "coal gas" is produced:\n\nC + O2 → CO2 \nCO2 + C → 2CO \nC + H2O → CO + H2 \n\n"Water gas" is a term used for a mixture of Carbon dioxide and Hydrogen made by mixing "Coke gas" with steam:\n\nCO + H2O → CO2 + H2

The molecules of water do not actually "change."  They vibrate faster as they get warmer.  If they are vibrating slowly enough, the molecules are packed closely together into the solid form of water we call ice.  As they move faster they become the liquid state we commonly call water.  When they are vibrating fast enough they "evaporate" into the gaseous state.  \nIn any of these 3 states they are still molecules of water, they are just moving around at different speeds.

The first question is not a basic question. It is not even a good question. "Ideal" is what you decide to call your model. It is your definition and you may use it as you see fit. I doubt your teacher wants that particular answer to the first question, but it is a true one.\n\nYou have the right idea for the second one, but you could describe it better. First, you must heat alcohol up to turn it into a gas, so you know that the gas has more internal energy... because you added some to make it gaseous. The reason that gas molecules tend to be spaced farther apart from each other than liquids is that increased energy causes atomic motion to increase. The atoms jiggle more and more until they jiggle away into a gaseous state, so, really, the molecules are farther apart because of an increased energy, not the other way around.

hmm no one answered this and ill give it a shot. \ntook AP chem last year but lets see what i can remember...\nsome possibilities:\nsplattering\nerror in massing\nOOOi think this is it: naphthaline is volatile [according to wikipedea], which means that it evaporates really easily. \nthats probably the answer u are loooking for.\nif u dont know what volatile means, look it up, ask ur teacher, or go on wikipedia.\nso basically the error would be that the mass of the naphthalene would be less after a period of time becuase some of it had evaporated.\n\n=P read more and figured out a nother problem:\nNaphthalene easily sublimes at room temperature without vacuum.\nsubliming = cahnge from solid to gas wiht no intermediate liquid phase.\nso i guess mroe of the mass is loss that way.\nseems like naphthalene like being a gas, huh? =P\n\nhope that helped

There are gasses dissolved in the fluid. When you stretch the joint the volume increases and therefore the pressure in that volume decreases. This allows to gas to come out of the liquid. It makes a noise like opening a bottle of soft drink. This is also the same principle that gives divers the bends if they come up too quick. \nThere is a name for the law, it is to do with dissolving gasses in a liquid under pressure. I am suffering a mental block, err henry's law?? russels?? errr.. some plain name like that anyway

Absorption describes the movement of a gas from the gas phase into a liquid. For example the absorption of acid gases into rain which result in acid rain.\nIt is effected by parameters like the pressure (increased pressure generally tends to give greater absorption i.e. more gas can move into the liquid - think of lemonade when you reduce the pressure by opening the bottle the CO2 undergoes the opposite of absorption, although some Co2 still remains dissolved). It is also effected by the temperature.\nIs is described by Henry's Law which, in simple terms, predicts the amount of a gas which will absorb into a liquid for a given pressure.

Of the SAME substance or different ones?\n\nAnd in what context?\n\n\nliquid, plasma, gas, solid, gel, sponge, degenerate gas, supercritical fluid.

A soap bubble falls to the bottom of an open tank filled with air. When the same tank is filled with gaseous carbon dioxide, a similar bubble floats.\n\nCabbage juice is placed in a large flask. Vinegar is added to the point of color change. Aqueous ammonia is then added to the point of color change. Vinegar is then added again to show the reversibility of the color change.

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).

I'm not sure your question makes sense.  Did you mean gas?  Gasoline reacts with oxygen to make lots of energy.  Water just dissolves a little oxygen.  You'll have to study chemistry if you want more detail.

Ignore First L.\n\nI don't think you can tell directly from the periodic table what is solid/liquid/gas. Typically the noble gases are, well, gases.

Yes the two are different in their chemical compositions. Liquid petrolium gas, commonly known as LPG is a derivative of petroleum and is generally used as cooking gas.

Pressure increases when dissolved gases come out of solution (leave their dissolved state and become a free gas).\n\nMany things will cause some of the dissolved carbon dioxide in soda to go from dissolved to gas form.  Heat, dissolving something in the soda that is more soluble than CO2 (like salt), impurities in the liquid, and shock or vibration - which create "nucleation" sites that the dissolved gas can collect around and become gaseous.\n\nShaking creates nucleation sites.

In order of decreasing concentration:\n\nNitrogen, oxygen, argon, water, and carbon dioxide

since vapourisation is a change in state, it can also be called the heat of vapourisation, q.\n\nΔS = q/T\n\nΔS = (30x1000)/(273.15+76.8)\n\nΔS = 85.73 J/mol/K\n\nThat answer is only correct to a certain degree, since the temprature changes during the process, but it does.  otherwise you have to do a lot of maths.
