On the basis of intermolecular energy and thermal energy explain why?
(i) a solid has rigidity but a liquid does not have rigidty.
(ii) gases have high compressibility but solids and liquids have poor compressibility.

On the basis of intermolcular forces and thermal energy ,explain why (i) a solid has rigidity but liquids do not have rigidity? (ii) gases have high compressibility but liquids and solids have poor compressibility ?

The gases have two principal specific heats but solids and liquied have only one specific heat. Why ?

Assertion:Pressure does not have any effect on solubility of solids in liquids. Reason : Solids and liquids are highly incompressible

When compared with solids and liquids, the gases have

Energy is needed when a solid at its melting point is converted into a liquid. Why ?

A substance 'X' having low melting point, does not conduct electricity in both solid and liquid state. 'X' can be :

Solids have properties like rigidity a definite shape and a define volume. If intermolecular forces are greater than thermal energy, substances exist as solid. Solids can be classified into two types. Crystalline solids and amorphous solids, Crystalline solids have regular arrangement of particles, definite geometric shapes, sharp melting points and definite heat of fusion. They are anisotropic and undergo clean cleavage. On the other hand, amorphous solid have no regular arrangement of particles, irregular shapes, melt over a range of temperature, no definite heat of fusion. They are isotropic and undergo irregular cleavage. The melting point of crystalline solids is sharp due to:
