Thermal expansion of solids is the least among the three states of matter due to

Options

A. high kinetic energy of molecules of solids.
B. close packing of molecules solids.
C. the vibratory motion and rotatory motion of molecules of solids.
D. the large intermolecular space present in solids.

Answer

B

Explanation

In solid, the molecules are closely packed due to forces of attraction and hence thermel expansion of solids is least among the three states of matter.
