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.

solids have particles fixed tightly together in rows so they can’t move. In liquids, the particles are touching but are free to move around each other like balls in a ball pool. In a gas ...

Does it feel like a solid, liquid, or gas? Leave the shaving cream blob out overnight ... Do you notice a difference in how the mixture feels? The cornstarch particles do not dissolve, but are ...

The focus is that matter, whether solid, liquid, or gas, is made up of particles; that dissolving and evaporation happen at the particle level; and that models can help explain these processes that we ...

Suspensions are widespread in industry and everyday life. By a suspension, materials scientists mean a liquid in which tiny, ...

A combination of oil, water and magnetic particles defies conventional wisdom by consistently taking on the shape of an urn 1. If you pour oil and water into an empty container, the two liquids ...

Materials scientists are measuring the rolling friction of tiny, micrometer-sized particles. These measurements permit them to better understand everyday products such as concrete.
