Properties of Solid & its type
The
properties are as follow
Melting point
It
is defined as “The process in
which the solid state is changed to the liquid state is called melting point.”
Exp: The melting
point of solid is so high due to strong intermolecular force among their atoms
and solid objects have regular shape due to this property.
Rigidity
In solid the molecules do not move freely due to strong intermolecular forces and have regular shape this is the reason that solid are rigid and this process is called rigidity.
Density
As
density is mass per unit of any substance.
Exp: The solid
has high density due to strong intermolecular forces therefore their volume are
lesser and density are higher.
Types of solid
There are
two types of solid
- Amorphous
- Crystalline
solids
1. Amorphous solid (A mean without and morphous means Shape)
A solid in which the particles are not regularly arranged in definite geometrical shape is called amorphous.
Examples: Glass, Wax, and gem stones etc. Glass is not true solid sometimes it is called upper cooled liquid.
2. Crystalline Solids
The solids in which the particles are arranged in a definite geometrical shape is called crystalline solids.
Examples: Crystalline solids are true solids because it has
all properties of solids. Such as rigidity, Sharpe melting and boiling point,
diamond, sodium chloride etc.
