Yes, squeezing of a sponge is called compression
Yes, solids are both dense and incompressible.
solids
The arrangement of particles are packed together.
Yes, you can compress gases, liquids, and solids. However, liquids and solids are MUCH less compressible than gases, and for many practical purposes you can consider them "incompressible". This means that a high pressure will only cause a very small change in volume.
The force exerted by solids when pulled is called tensile force.
They are both incompressible, and they have a fixed volume at a fixed temperature.
tension and compression
molecular structure
Gasses are compressible and liquids and solids are incompressible. Using this information one can surmise that CO2 compressible would be the gas phase of CO2 and CO2 incompressible would be the solid (dry ice) phase of CO2.
Tension is a pulling force that is exerted by solids.
Solids. They are most resistant to outer forces; but strictly speaking all materials are compressible.
gases are highly compressible as there molecules have lots of spaces between them while in molecules of solids there is not much space and they are tightly packed .
