1.	Thermal exparision of solids is the least among the three states of matter due to
Answer» high kinetic ENERGY of molecules of solids. close packing of molecules solids. the vibratory motion and rotatory motion of molecules of solids. the large intermolecular SPACE present in solids. SOLUTION :In solid the molecules are closely packed due to strong FORCES of attraction and hance thermal expansion of solid is least among the three state states of matter.
