Can a Substance go directly from a solid to a gas? Explain.?

Yes, its called sublimation. It has to do with temperature and pressure. If you make CO2 (carbon dioxide) into a solid under really low temperatures and high pressure then when you take it out of the high pressure it will go directly into the gas phase.

Solid. Most elements at standard atmospheric temperature and pressure are solids. Some of the non-metals are gases, but only Mercury and Bromine are liquids at STP.\n\nEDIT: Gloo-gal, why answer if you don't know or don't care?

After looking over the literature I have available, I can't come up with one.  None of the noble gases would, and other gases such as nitrogen are nonreactive as well.  That's why they state to run certain reactions in a nitrogen atmosphere.\n\nNoble gases are able to react with some materials, but they often contain halogens, which are highly reactive.  Check out the links to see some compounds of xenon and krypton.

Matter can exist in either a liquid, solid, or gaseous state.  \nA) Iron nail is a solid\nB) Gasoline is a liquid unless you are speaking of the fumes that can be seen or smelled and then it is a gaseous state.

false....the gaseous state has the lowest levels of attraction.  (the molecules are the farthest apart in that state)...in solid state there are metallic or ionic bonds as well as Van Der Waals forces holding the mass together.

A real gas is a form of matter that will conform to the sides of its container.  As it is compressed its temperature increases.  It is the only form of matter than can be compressed at all.  Gas is the least organized form of matter.

It's not actually evaporation.  It's sublimation; the change of phase is directly from solid to gas.

You really should write a more detailed question.  But I think you're asking "why do things melt and boil?"\nA solid will convert into a liquid when the Intermolecular forces are over come by the raising average Kinetic engery(Temperature) and then it boils when those forces are over come enough to break away and become a gas.

The phrasing is wierd, shouldn't there be a from between flow and the?\n\nIf two substances have different _temperatures_, heat will flow [from] the hotter [substance] to the colder [substance].\n\nThis is because heat, at the molecular level, is related to how fast molecules are moving. When a substance whose molecules are moving faster comes in contact with an object that's moving slower, the faster molecules will collide with the slower molecules of the second object, slowing down the faster molecules while speeding up the slower ones. Thus, heat (average kinetic energy of a substance) is transferred from the hotter substance to the colder one.

all things have a solid liquid and gas state. it just depends on the temperature.

Everything goes from solid to whatever else one molecule at a time. It's just that under certain conditions, there is a spread between the energy that it takes to get away from the solid and the energy that it takes to exist as a gas. So, when you melt ice under one set of conditions, the molecules only have enough energy to break free from the ice crystals and go into solution. But, if the pressure is very low (outer space say) then that same amount of energy is enough to drive the water molecules into the gaseous phase instead.

Most substances actually have a "critical point," where at a specific temperature and pressure, they exist in all three states in a tri-equilibrium. For a more practical example, a snowcone sitting in the hot sun would probably qualify as a mixture of all three, though not an even mixture, and not at any real sort of equilibrium. Matter as plasma exists as high energy charged ions, so you're probably not going get that mixed in with the other three, though you can get a mixture of plasma and one other, most likely. But then, it's not like we run into plasma very often anyway.\n\nEDIT: Plasma has to change from something, so you're going to get a mixture at least while the matter changes to plasma from its earlier state, for however long that transition lasts. A stable mixture would be a lot more rare, but more likely to succeed as a gas/plasma mix than anything else.

Water, when heated from a solid to liquid state, but ultimately in a gaseous state it again expands.  It still obeys all the laws of chemistry, but the bonds just arrange themselves in a more space efficient manner in liquid than in solid form.\n\nAnd moses with a P, no metals exist with the properties you say.  It is physically impossible, sorry man, but I'm a biochem major and it's my job to know what stuff does under different stresses, and nothing does what you claim.  However, if you do have a material that does this, get in touch with me, we'll talk to the patent office, and we'll license it out to companies for billions of dollars.

Radiation energy keeps the atoms appart othe wise every atom would kiss each other. If you remoave this radation energy by cooling the atoms would come closer and closer till they form a tight  bond.Athat point the gas has changed its personality=it is said it changed phase and it beomes a solid. but it can only remain that way depending  at what temperature a pressure its existing.\nAs soon as you inject heat the gas return into its natural steady state.Phases of substance are convertible.\nhowver, we live in a world of equilibrium which makes our existence possible.\nif this mechanisn of material phase equilibrium protection was not in place we would all turn to solid matter.

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.

With most substances high pressures help it form from gas to liquid to solid.  But with water high pressure between liquid and solid the transition is harder to make happen.  This is due the expansion of water when freezing.

Yes you are correct.Different substances are different because of  their molecular structure and the constituents of each molecule. Molecules are well bound together in solids than in fluids (gases and liquids). The molecules are free in gases.\n Further the molecules are not at rest and are in vibrations.When the substance is heated  the average energy of a molecule  increases which tend to decrease the bindings of the molecules.\nGenerally by heating , a substance  chnges from solid to liquid and then to gaseous state.We call this as physical change.\nWhen the energy is  strong enough to break the  molecules into its constituent elements new compounds are produced we call it as chemical change.\nIn effect heat  has many things to do with their bondings
