1 Polymorphism
2 Isomorphism
3 Allotropy
4 Enantiomorphism
Explanation:
\((a)\) The existence of a substance in more than one crystalline form is known as polymorphism.
The Solid State
31873
Which is not a property of solids
1 Solids are always crystalline in nature
2 Solids have high density and low compressibility
3 The diffusion of solids is very slow
4 Solids have definite volume
Explanation:
\((a)\) Solids are also non-crystalline in nature.
The Solid State
31874
Which solid will have the weakest intermolecular forces
1 Ice
2 Phosphorus
3 Naphthalene
4 Sodium fluoride
Explanation:
\((a)\) Ice has the lowest melting point out of the given solids, hence it has the weakest intermolecular forces.
The Solid State
31875
Dulong and Petit’s law is valid only for
1 Metals
2 Non-metals
3 Gaseous elements
4 Solid elements
Explanation:
According to this law, the product of atomic mass and specific heat of a solid element is approximately equal to \(6.4 \,cal / mol\). This law is valid for solid elements only.
