2 Changes abruptly from solid to liquid when heated
3 Has no definite melting point
4 Undergoes deformation of its geometry easily
Explanation:
In crystalline solid, there is perfect arrangement of the constituent particles only at \(0 \mathrm{~K}\). As the temperature increases, the chance that a lattice site may be unoccupied by an ion increases, as the number of defects increases with temperature, solid is changed into liquid.

Statement A : True solids are anisotropic. Statement B : True solids have short range order in arrangement of constituent particles.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
True solids are anisotropic due to long range order in arrangement of constituent particles.

Silicon carbide is an example of
1 molecular solid
2 metallic solid
3 ionic crystal
4 covalent solid
Explanation:
Silicon carbide \({\text{(SiC)}}\) is an example of covalent solids. Covalent or network solids are crystalline solids of non-metals that result from the formation of covalent bonds between adjacent atoms throughout the crystal. They are insulators and do not conduct electricity.
