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 ...
In physics, a state of matter is one of the distinct forms in which matter can exist. Four states of matter are observable in everyday life: solid, liquid, gas, and plasma.
Aug 19, 2020 · Learn about the four main states of matter (solids, liquids, gases, and plasma) and their properties. Also, discover other states of matter that exist under extreme conditions, such as Bose-Einstein condensate and photonic matter.
Learn what matter is and how it can be classified into solid, liquid and gas states based on intermolecular forces and particle arrangement. See examples of each state and how they can be converted by changing temperature and pressure.
Jun 19, 2020 · List the three states of matter and give examples of each. Describe the properties of each state of matter. Identify and describe each type of change in state. Recognize that boiling and melting points vary with each substance. Recognize that a substance's boiling point depends on the pressure.
