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 ...

Although the three states of matter are solid, liquid, and gas, not all substances seem to fit perfectly ... Do you notice a difference in how the mixture feels? The cornstarch particles do not ...

In solids-handling, blending (combining two or more materials to achieve a combined product) and segregation (the separation of particles into distinct zones according to ...

A newly developed process transforms large ... spherical particles that act like tiny ball bearings rolling past one another. This allows solid metals to be handled like liquids.

Students explore the attractions and motion of atoms and molecules as they experiment with and observe the heating and cooling of a solid, liquid, and gas.
