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 ...

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 ...

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 ...

Earlier this week we broke down the complexities of mixed-phase precipitation forecasting.Within that we briefly touched on a key component to that complexity w ...

Here is a new material capable of behaving like a liquid under low pressure, then solidifying instantly upon impact.

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 ...

Is industrial agriculture both ruining air quality and delaying climate change? Aerosols—suspensions of fine solid particles ...

Although gas-solid systems are characterized by the same mechanical interactions that are present in granular flows (e.g., collisions between two particles), the physical nature of the gas-solid ...

The reason is, that the particles of air or gas, far from being under the influence of cohesive attraction, like solids or liquids, are actuated by a powerful repulsion for each other. The ...

and uses chainmail-like design with entangled rings in place of fixed particles typically found in a crystalline structure. Because of its not-quite-liquid-not-quite-solid nature, PAMs are ...
