Question

Comment ·on the following statement

Sponge though compressible is a solid.

Answer 1

• A solid can be defined as a substance which exists in the solid state, which is one of the four fundamental states of matter.
• Solids feature closely packed atoms whose kinetic energies are much lower than those of liquids and gases.
• All solids have rigid structures that tend to resist any external forces applied to them.
• Solids also are known to have a fixed, definite shape (unlike liquids and gases, which assume the shape of the container they are placed in).
• Solids do not have the ability to flow as liquids and gases do.
• The atoms of a solid can be bound together in either a regular or an irregular manner.
• Sponge is basically a solid.
• However, it has very fine holes which are called pin holes.
• Air gets trapped in these holes and the size of the sponge somewhat increases.
• On compressing, air escapes from the pores or holes and the size of the sponge decreases.
