There are 1 common states or phases of matter in the Universe: solid, 2 , gas, and

3 . The state of matter affects a substance's 4 , such as 5 , viscosity (how well it flows), malleability (how easy it is to bend), and conductivity (how well it carries heat or electricity).


Common States of Matter



In a solid, the positions of atoms are 6 relative to each other over long time. That is due to the cohesion or "friction" between molecules. This cohesion is provided by metallic, covalent or ionic 7 . Only solids can be pushed on by a force without changing 8 , which means that they can be resistant to deformation. Solids also tend to be strong enough to hold their own shape in a 9 . Solids are generally 10 than liquids. Solid becoming a 11 is sublimation.



In a liquid, molecules are 12 to other molecules strongly enough to keep molecules in

13 , but not strong enough to 14 a particular 15 . The molecules can continually 16 with respect to each other. This means that liquids can 17 smoothly, but not as smoothly as gases. Liquids will tend to take the 18 of a container that they are in. Liquids are generally less 19 than solids, but denser than gases.
