Which two of the three states of matter are not very compressible?

Which two of the three states of matter are not very compressible?

Key Points

• Solids are non-compressible and have constant volume and constant shape.
• Liquids are non-compressible and have constant volume but can change shape.
• Gases do not have a constant volume or shape; they not only take the shape of the container they are in, they try to fill the entire container.

Why are solid incompressible?

The constituent particles of a solid are very closely packed. The inter-particle distances are so small that if we try to bring them closer, repulsions start between their electron clouds. Hence, they are incompressible .

What solid can flow?

Granular materials are solids that can flow and behave like liquids. Examples of granular materials include sand, coffee, nuts, even corn flakes. Scientists consider things like icebergs or asteroids to be large granular materials, due to how they behave.

What form does solid flow?

There are several modes of solids flow in a hopper: funnel flow, mass flow, etc. Funnel flow would have an annular zone of stationary solids and a moving core of solids at the center. In this case, the solids flow primarily through the core of the hopper. Solids in the periphery either remain stationary (Fig.

Can a solid act like a fluid?

For a granular material to behave like a liquid there must be many, many grains close together. For example, a single boulder rolling down a hill is not acting like a liquid; but thousands of rocks, boulders and dirt particles flowing down a hill during a landslide do behave like a liquid.

Can a solid change shape?

Changing shape Most solids change their shape if they are squeezed or pulled with enough force. The particles in the solid cannot move closer together, but they can often slide around and past each other if they are pushed hard enough. Thin bars and sheets of solids can often be bent or molded.
