Figure \(\PageIndex{3}\): Why Liquids Flow. Molecules in a liquid are in constant motion. Consequently, when the flask is tilted, molecules move to the left and down due to the force of gravity, and the openings are occupied by other molecules. The result is a net flow of liquid out of the container. (CC BY-SA-NC; Anonymous vy request).
Sep 24, 2021 · Figure 6.1.4 6.1. 4: Solid, liquid, and gas states with the terms for each change of state that occurs between them. Liquid evaporates into gas in freezes into a solid; gas condenses into a liquid depositions into a solid; solids melt into a liquid and sublimation into a gas.

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 ...
- Matter is everything around us. Matter can be a confusing word because it has several meanings. We often hear phrases like “What is the matter?” or “It doesn’t matter”.
- Solid. Right now, you are probably sitting on a chair, using a mouse or a keyboard that is resting on a desk – all these things are solids. Something is usually described as a solid if it can hold its own shape and is hard to compress (squash).
- Liquid. The simplest way to determine if something is a liquid is to ask this question: If I try and move it from one container to another (i.e. by pouring), will it conform to (take on the shape of) the new container?
- Gas. The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape.
Forces. of attraction between the particles hold them together and keep them in place. The particles in solids are arranged in a regular way. The particles in solids move only by vibrating about a ...
