MATTER
IS ANYTHING THAT OCCUPIES SPACE.It includes everything
from natural substances, such as minerals or living
organisms,to synthetic materials .Matter can exist in three
distinct states -solid, liquid,and gas.A solid is a rigid
and retains its shape.A liquid is a fluid , has a definite
volume,
and will take the shape of a container . A gas fills a space , its volume will be the same as the volume of its container .Most substances can exist as a solid ,a liquid, or a gas; the state is determined by temperature.At very high temperatures, matter becomes plasma , often considered to be a fourth state of matter.All matter is composed of microscopic particles , such as atoms and molecules.The arrangement and interaction of these particles give a substance its physical and chemical properties , by which a matter can be identify.There is a huge variety matter because particles can arrange themselves in countless ways ,in one substance or by mixing with others .Natural glass ,for example , seems to be a solid but is ,in fact , a super cooled liquid ;the atoms are not locked into a pattern and can flow.
Pure substances known as elements combine to form compound or mixture..Mixtures called colloids. are made up of larger particles of matter suspended in a solid ,liquid, or gas, while a solution is one substance dissolved in another.
CHANGING STATES OF WATER
.
SOLID STATE -ICE,
LIQUID-STATE-WATER.
GASEOUS STATE-STEAM.
The solid state of water ice,forms ,when liquid water is cooled sufficiently.
When temperature of a substance rises above its freezing point ,it melts to become a liquid.Ice changes to water.
Above its boiling point ,a substance will become a gas.When
heated sufficiently liquid water turns to steam, a colour less gas.
