Solids, liquids and gases. In a solid like this brick, the particles are regularly arranged touching their neighbours and move only by vibrating. This explains why solids have a fixed shape. In a ...

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.

THE tenets of physics can seem carved in stone. The speed of light is a constant. There are four fundamental forces. Theoretically, rules like these are open to revision. But new contenders had better ...

Physicists are now watching matter behave in a way that defies everyday intuition, with atoms and even light itself arranging into structures that are rigid like a crystal yet able to flow like a ...

We explore Supercritical Fluids and how being "in the between" is their superpower. Supercritical Fluids are one the strangest states of matter and yet they are found everywhere from Decaf Coffee, to ...

Some atoms in a liquid stay fixed even at high temperatures, reshaping how solidification starts and enabling an unusual corralled supercooled liquid state. (Nanowerk News) Researchers have discovered ...

Students are introduced to the idea that matter is composed of atoms and molecules that are attracted to each other and in constant motion. Students explore the attractions and motion of atoms and ...
