compare a block of wood water and air on the basis of the following compressibility particle motion rigidity
Answers
Explanation:
A block of wood is a solid substance, water is a liquid substance and air is a gaseous substance.
In a solid, the molecules have strong intermolecular force of attraction and are closely packed to each other. As a result, there compressibility is very less, particles only vibrate at their mean position and solids have high rigidity that is they have inability to move from their respective position.
In liquids, the molecules have less intermolecular force of attraction between the molecules and are less tightly packed to each other. As a result, the particles have more compressibility as compared to solids, particles move from one place to another, and liquids are also less rigid as compared to solids.
In gases, the molecules are loosely held as there is no intermolecular force of attraction between the particles. As a result, gases are highly compressible as compared to solids and liquids. Motion of particles is very rapid and continuous, and gases are not rigid as they have the ability to easily move from one place to another.
