Gas: Materials in this phase have no definite volume nor shape. Many devices make use of liquid crystals, including cell phones, TVs and digital clocks. Soapy water is an example of a common liquid crystal. Their molecular structure, however, better resembles solid crystals. They appear to be a liquid and flow like a liquid. Within the most common phases of matter, other states may appear. When heated enough, it will usually become a gas. Water, shampoo and milk are all examples of liquids.Ĭompared to the atoms and molecules in a solid, those in a liquid are usually less tightly packed together. But it will not expand to fill the entire container holding it. A liquid will take the shape of any container into which it’s poured. Squeezing a liquid will not compress it into a smaller volume. Liquid: Materials in this state have a definite volume but no defined shape. Or it might sublimate - turn directly from solid to gas when brought to certain temperatures or pressures. They’re so tightly bound that they do not move freely. The atoms and molecules that make up a solid are tightly packed together. A desk, phone and tree are all examples of matter in its solid form. And they’ll maintain their shape without the help of a container. That is, they take up a set amount of space. Solid: Materials in this state have a definite volume and shape. While there’s likely more awaiting discovery, below are seven of the currently agreed-upon states that matter can take. (They can only be created by scientists in a laboratory.) Even today, researchers are still discovering new states of matter. Lesser-known states develop under more extreme conditions - some of which never exist naturally on Earth. Solid, liquid and gas are the best-known states of matter.

This diagram illustrates the cycle of the states of matter using H2O as an example. When these tiny building blocks of matter change their structure, their state or phase does too. All matter is made of atoms and/or molecules. However, water isn’t the only type of matter that changes states as it’s heated, cooled or compressed. In ancient Greece, one philosopher recognized how water could change form and reasoned that everything must be made of water. Solid (the ice), liquid (the water) and gas (the vapor) are the three most common states of matter - at least on Earth. This vapor is still H 2O, just in gas form. If it gets hot enough, you will notice steam rising off of the liquid. Put the ice into a pot over a flame on the stove and it will melt back down to liquid. The substance in the tray is still the same chemical - H 2O only its state has changed. Pour water into the tray, stick it in the freezer and a few hours later that liquid water will have transformed into solid ice. Like other substances, water can take different forms as its surrounding environment changes. For example, frozen nitrogen will form both the liquid phase and the vapor phase when exposed to normal temperature and pressure.Ice, water and vapor are three distinctly different forms - or states - of water. Multiple phase changes can occur at once. For example, if you view the sublimation of dry ice into carbon dioxide gas, the white vapor that is observed is mostly water that is condensing from water vapor in the air into fog droplets. Phase changes aren't always clear when observing a situation. Plasma most often forms from ionization of a gas, although if sufficient energy and enough space are available, it's presumably possible for a liquid or solid to ionize directly into a gas. Plasma: Plasma can recombine to form a gas. Gases form from the sublimation of solids, vaporization of liquids, and recombination of plasma. Gases: Gases can ionize into plasma, condense into liquids, or undergo deposition into solids. Liquids form by condensation of gases and melting of solids. Liquids: Liquids can vaporize into gases or freeze into solids.
Solids form by deposition from gases or freezing of liquids. Solids: Solids can melt into liquids or sublime into gases. Another way to list phase changes is by states of matter:
