The state of matter is a deceptively simple concept ... These are categories of stuff that have certain observable properties. Solids have their own defined shape that won’t change without ...

quantum mechanics introduces new and unusual phases of matter. One of these is the supersolid—a state that retains the structured, rigid properties of a solid while also flowing without friction ...

Understanding Supersolids A supersolid is a paradoxical state of matter that maintains a crystalline structure like a solid while also flowing without resistance, a property typical of superfluids ...

There are three main states of matter: solid, liquid and gas. When a substance changes state, this is a physical change because no new substances are produced and the change is reversible.

For the first time ever, scientists have turned light into a supersolid — a bizarre state of matter that acts both like a solid and a liquid (Science, March 5). Scientists achieved this feat ...

Solids, liquids and gases are called the three states of matter. Liquids can flow or be poured easily. They are not easy to hold. Liquids change their shape depending on the container they are in.
