Explanation / Answer

1) Ceramic- because it has good electrical insulating properties and high thermal conductivity.

2)Thermoset material has a mixture of secondary and covalent bonding

3)interstitial defect

4)larger grain have lower strength because they have fewer grain boundaries and small stress is enough to collapse the grain boundary.

5)They have high modulus value due to their high bonding
