What happens to particles of matter when a liquid becomes a gas?
155067
The liquid molecules begin to heat up which causes them to increase their moleculer movement. They eventually move very far apart which causes them to be in the "gas" state.

Molecules vibrate. As they vibrate faster, matter expands. The vibration is this energy we call heat. When vibration is lowered to a certain levels, matter becomes solid (water freezes), at the other end of the spectrum, when molecules agitate at a certain speed, liquids turn into gas (water evaporates).

A ton. Let's take everyday physics first: The answer depends very much on how you define a state of matter. Glas is a good example: It feels like a solid, but it is not made up of crystals with atoms placed in a regular array like in a salt crystal and most other solid states. The atoms are randomly spread around more like in a liquid (in fact during many years a glass window will get thicker at the bottom than at the top, because glass is really a kind of liquid - a solid liquid if you wish). So you can call glass a differnent state if you wish.\n\nNow let's go to extremes:\nThe plasma state arises when the temperature gets so high that atoms cannot bind the electrons any more (so electrons and nuclei are floating freely around among each other). If you go to really really extremely high particle energies (so high that even modern particle accelerators can only barely make it) also the nuclei will finally be decomposed into constituents called quarks and gluons creating a new state called a quark-gluon plasma. More info:\nhttp://en.wikipedia.org/wiki/Quark_gluon_plasma\n\nIf you go to very very low temperatures quantum mechanical features of atoms begin to become important and a lot of new, interesting states of matter emerge (quantum mechanics is the physical laws valid on the atomic level. It is very different from Newtons laws). For instance liquid helium - when cooled below a critical point (which is about 2 K) - changes it state from a normal liquid to a so called superfluid liquid which among a lot of other interesting features does not experience any frictional forces (so it can crawl over the walls of a cup for instance). What goes on is that all the atoms (or at least many of them) unify and moves together - in a sense the collection of atoms behaves like it was only one atom. Such a collection of atoms behaving almost like a single atom is called a Bose-Einstein Condensate and it is clearly a new state of matter. Nowadays Bose-Einstein condensates of many different kind of atoms can be created in a controlled manner in modern laser laboratories. The Nobel prize in physics in 2001 was awarded for the first realization of this, a lot of information can be found on\nhttp://nobelprize.org/nobel_prizes/physics/laureates/2001\nIt is a similar phenomena that leads to superconductivity in some materials at very low temperatures, by the way. A lot of modern research deals with understanding exotic quantum states of matter and create them in laboratories.\nI hope the answer helps. I have tried to make it as understandable as possible, but quantum states of matter is a difficult topic.

As temperature goes up particle (atoms) move faster and as they move around they "bounce" off each other. Thus they expand and get bigger. Thus gas expand when heated. Solid become liquid and liquid become gas... The opposite is true. As temperature decrease, atoms slow down and bump less. Area is decrease as each atom need less space. Not a very scientific answer and may not get the best answer reward but that is the jist of it.

Matter can exist in several different phases, according to particle density and energy density or alternatively pressure and temperature. These phases include gases, plasmas, liquids, fluids, superfluids, solids, and Bose-Einstein condensates.

Gases disperse to fill whatever container they occupy.   Gases are composed of matter and thus occupy space.  Since no two objects of matter can occupy the same space at the same time and a gas expands to occupy a given space a force(pressure) exist.  As the temperature increases the pressure increases because you are adding energy to the system.

Two things make a difference here. The average distance that an individual particle is likely to move before it bangs into another particle and the speed at which the particles are moving.\n\nBecause the space between particles is so much larger in a gas than in a liquid at the same temperature, the "free path length" is longer in a gas and the diffusing substance is typically able to move further in a given period of time.  Therefore, gases diffuse through gases much more rapidly than liquids through liquids if all else is equal.\n\nFor any given combination, the hot gas or liquid substrate will provide more rapid diffusion compared to the cold one due to particle speed.\n\nYou need to check out Graham's Law of Diffusion if you want to get mathematical about this.

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).

No, nothing has to melt before it evaporates.  The factors that control the states of matter are pressure and temperature. in a vaccum water will evap at cool temps, in high temps water will evap, in extreme temperatures under extremes vac. solids are liable to sublimate into gas.  It can happen under the right conditions, solid CO2 goes from solid to gas at room temp under 1atm of pressure

the water is relesed as vapor from the liquid when the liquid is heated. Water changes phase and becomes gas, its called evaporation.

if the water is at very very low pressure it can become gaseous.\n\nSee also - the triple point of water

in a liquid-they have no distinct order and move freely but cramped.\nin a solid-they are in a fixed position.\nin a gas-they move freely and are extremely active\nin plasma- they move like gasses and liquids

The atoms of iron begin to move at a more rapid pace, causing the material to expand.  Once it expands enough there is so much energy that it can turn into liquid form, allowing it to flow freely so long as another force isn't standing in it's way.  The same thing happens to all matter when heated up.  You may even notice that the metal will begin to glow.  This is because of radiation in the form of photon particles.  It will also become highly ductile and maliable, which are two characteristics that iron have.  Heck, if iron were to be heated up far enough it could even become a gas.  However, I doubt you would ever be able to do it without both heat and compression with current technology.  You might even cause the gasses in the atmosphere around it to gain enough energy to start a fusion reaction, which could cause one yucky mess out of our atmosphere if they don't cool down.

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.

u see,when a solid is heated to a certain extent it melts into liquid,and further heated it becomes a vapour,when it is heated to a greater extent,the molecules break up into atoms and atoms into very minute states.these form a cloud of particles which is called plasma.\n          for ex.,the temp. of stars is upto millions of degrees hence the plasma is present and also known as fourth state of matter.\n        i hope u got it!!!

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.
