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 ...

She explains that, unlike the well-defined categories of solid crystalline lattices and granular materials like rice or coffee, PAMs combine aspects of both. The particles in PAMs are linked like ...

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 ...

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.
