The document describes the solid state of matter, characterized by closely packed particles that have a fixed shape, mass, and volume. It outlines key properties of solids, including their incompressibility, high density, and strong interparticle forces. Examples of solids include building materials, dry ice, ice, metals, minerals, and salt.

2. What is Solid state?
●
Solid is a state of matter in which the constituent
particles are very closely packed together.
●
A solid is that state of matter which has a fixed shape,
mass, and volume.

3. Properties of Solids
●
Solid has a fixed shape and a fixed volume.
●
Solid cannot be compressed.
●
Solids have a high density.
●
Force of attraction between the particles in a solid is
very strong.
●
The space between the particles of solids is negligible.

4. Interparticle in Solids
●
Interparticale force of
attraction is highest.
●
Interparticale space is
least.
●
The molecules of solid
are attracted together and
vibrated at thier fixed
position.

5. Examples of Solids
bricks and other building materials, like concrete,
wood and glass;
dry ice or frozen carbon dioxide;
ice;
most metals;
most minerals;
rocks; and.
salt.
