We all know from middle school science class that matter changes between a solid, a liquid, and a gas when you change the temperature or pressure acting on it. (Yes, some elements will change directly ...

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 ...

Researchers report that the way a tissue's cells are arranged can serve as a fingerprint for the tissue's 'phase' -- whether it is more like a solid, liquid, or gas. For example, tumors that are more ...

Scientists have discovered a new state of matter that isn't a solid, liquid, or gas. Researchers call this new type of material a 'corralled supercooled liquid'. Atoms in a liquid are normally like ...

Almost everything is made of particles. Particles can be atoms, molecules or ions. Particles behave differently in solids, liquids and gases. The particle model explains the differences between solids ...
