1. States of
the Matter
Lesson 1

3. States of matter means different or distinct characteristics
and properties a matter can exhibit. It is also known as
the phases of matter. In general, there are three states of
matter, i.e., solid, liquid, and gas. Every state of matter
has unique properties in very different environmental
conditions which form the basis of the classification. Every
state of matter is exhibited around us from a solid sofa to
liquid cold drinks and from water to gaseous air that we
breathe. Every state of matter has an essential part in the
environment and our day-to-day life. Matter is anything
that occupies space and has weight.

4. Solids
• Solids are tough and have a rigid shape which implies that they
cannot be molded into other shapes easily.
• They occupy a definite space.
• Have a fixed shape and volume.
• Have high intermolecular attraction and less or no space
between consecutive molecules which provides them rigidity.
• Do not tend to flow like liquids and cannot be easily
compressed.
Example - wood, ice, brick, stone.

6. Liquids
• Liquids have fixed volume but do not have a fixed
shape. They occupy space and change their shape
according to the container they are placed in.
• They have a higher density, and more intermolecular
space between them, unlike solids.
• The liquid particles can flow easily and freely.
• Can be compressed to a certain extent.
Examples - blood, water, milk, coffee.

8. Gas
• They neither have a fixed volume nor a fixed shape.
• They have much less intermolecular space between
them compared to solids as well as liquids.
• Gases are easily liquefied or compressed.
• They fill the space complete in which they are kept.
• Particles have very little interaction and are
randomly moving.
Examples - oxygen, carbon dioxide, neon, etc.

10. DIFFERENCES BETWEEN DIFFERENT STATES OF
MATTER
Properties Solids Liquids Gases
Mass Definite Definite Definite
Shape Definite Acquires the shape of the
container
Acquires the shape of the
container
Volume Definite Definite Indefinite
Compressibility Not possible Almost negligible Highly negligible
Fluidity Not possible Can flow Can flow
Rigidty Highly rigid Less rigid Not rigid
Diffusion Slow Fast Very fast
Spaces between particles Most closely packed Less closely packed Least closely packed
Interparticle forces Definite Slightly water than solid negligible

11. SPECIAL PROPERTIES OF MATTER
•Porosity is the property of a material to absorb liquid like
water. To absorb liquid like water. Porous materials have
plenty of spaces or holes called pores where liquid can be
quickly absorbed
•The ability of materials to absorb water is due to the
presence of loose fibers with lots of pores or holes between
the particles that make up the materials.
•In sponge, for example, these hole or pores absorb water,
making the sponge swell. When you are cooking, you make
sure that materials are clean before using them.

12. • When you squeeze the sponges, you are forcing the water or liquid cleanser
out of the holes that cleans the surface of the dishes, glasses or spoons that
you washed and used in cooking.
• Other materials that absorb water like tissue paper, cottons, and cloth are
called porous materials. These materials can easily undergo decay also. This
happens because the presence of water or moist in the materials can cause
degradation of the materials due to presence of microorganisms that
harbors or pile up in the materials.
• Materials like plastics or metal spoons and forks. Porcelains, cups, iron nails,
aluminum cook wares and glasses that you used at home do not absorb
water or liquid, hence, they are called non-porous materials. There are no
holes or spaces between their particles.

13. The ability of materials to sink or float in water
depends on their density.
Remember:
If the density of an object is higher than the
density of water, that object will sink in water.
But if the density of the object is less than the
density of water, the object will float in water.
