This model explains the higher density, greater order, and lower compressibility of liquids versus gases; the thermal expansion of liquids; why they diffuse; and why they adopt the shape (but not the volume) of their containers.

Particles behave differently in solids, liquids and gases. The particle model explains the differences between solids, liquids and gases.
The particles in a liquid are: close together, but slightly more loosely packed than solids. arranged in a random way. Particles in a liquid. The particles in a liquid can: flow around each other.

You can change any substance from a solid to a liquid or gas, or back again, just by changing its pressure and/or temperature, but that's not immediately obvious to us in a world where the temperature and pressure don't change much at all. On Earth, temperatures broadly vary from about −30°C to +30°C or (−70°F to +90°F)—which seems a huge variation...
Another way to understand solids, liquids, and gases is by thinking about the energy they contain. A balloon full of gas has molecules dashing about inside it, smashing repeatedly into the rubberwalls and pressing them outward. Balloons stay up because the force of the gas molecules pushing against the inner surface of the rubber exerts a pressure ...
What if you cool down a balloon—and keep cooling? Suppose you fill your balloon with steam to start with. Cool it for a while and you'd get a balloon with a bit of water inside, then a balloon frozen with ice. If you keep on cooling, you take more and more energy from the molecules inside. Even the atoms or molecules in a solid do move about a litt...
A solid lump of iron is much heavier than a glass of water the same size, while a balloon that's many times bigger seems to weigh nothing at all. Some solids, such as rubber, are very stretchy: you can pull a rubber band to two or three times its length and it will snap straight back to its original length when you let go. Other solids (like glass ...
If you heat a liquid, sooner or later you get a gas—but what happens if you keep heating? Eventually you produce a fourth state of matter called a plasma, in which the gas molecules not only separate from one another but break apart into their subatomic components—electrons and ions (in this case, atoms missing electrons). Plasmas are used in plasm...
I've just broken the "bad" news that there are four states of matter, not three. But is that the end of the story?Nope! There are a few others that exist only under extreme conditions. The best known of theseare called Bose-Einstein condensates (in honor of physicists Albert Einstein and Satyendra Nath Bose). They're formed when special gases made ...
Aug 11, 2016 · If the particles of a substance have enough energy to completely overcome intermolecular interactions, then the particles can separate from each other and move about randomly in space. Like liquids, gases have no definite shape, but unlike solids and liquids, gases have no definite volume either.
The liquid state can be thought of as the intermediate state between solids and gases. There are attractive forces between particles in the liquid state; but they are rather weak forces when compared to solids.
Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. The following figure illustrates the microscopic differences.
