Question

hard substances generally breaker when compressed explain with example​

Answer 1

Answer:

Crystalline solids are generally the true solids. In solids, the molecules are tightly packed together and that's why solids keep their shape. Because the molecules in solids are not allowed to move freely, therefore hard substances have a fixed shape that is impossible to change.

Generally, hard substance breaks apart when high tensile strength is applied to them and neither can be compressed, into smaller pieces, nor modified.

Example:

Sodium chloride is a hard substance that breaks apart under high pressure.

Answer 2

Hard substances break when compressed because the force applied breaks the molecular forces of the hard substances and breaks them into pieces.

EXPLANATION:

Hard substances usually have molecules closely packed together and have fixed shapes. It is not easy to break the molecular forces of hard substances. When high tensile strength is applied during compression of hard substances, they break into smaller pieces. The hard substances break because they cannot be compressed and their shape also cannot be changed.
