Which of the following statements is NOT true regarding the general characteristics of solids?
Solids have definite volume.
Solids have definite shape.
Solids are highly compressible.
Solids have high density.
Solids are characterised by having a definite shape and a definite volume, meaning that they do not change shape or volume easily. This is due to the close packing of particles in a solid, which makes it difficult to change the arrangement of particles without breaking the solid apart. This also leads to solids having high density since the particles are packed closely together.
Unlike gases, solids are not highly compressible because their particles are already tightly packed together. The intermolecular forces between the particles in a solid prevent them from being easily compressed or expanded. Thus, statement c) is false, and the correct statement is that solids are not highly compressible.
