CHAPTER 5:

5.1 WHAT IS A MATTER?

Substance that has mass
and occupies space

Almost everything Living things
In nature is a matter Non-living thing

PROPERTIES

PHYSICAL PROPERTIES OF MATTER

- Properties that can be identified by our five senses or measuring tools

1-Heat conductor and heat insulator
2- Boiling point and Melting point

4-Density

CHEMICAL PROPERTIES OF MATTER

- Properties that become evident when it changes to a new
substance

1-Rusting

Rusting occurs on iron when
it is exposed to water and air

5.2 THREE STATES OF MATTER

1)Characteristic
2)Diffusion rate
3)Changes in the state
4)Examples of change of

state of matter

MATTER

Made up of tiny particles which are
discrete and always moving around

STATES OF MATTER

solid liquid gas

DIFFUSION

Process in which the particles of substances diffuse

from high concentration area to a low
concentration area



DIFFUSION RATE IN
THREE STATES OF MATTER

is is
slow the highest

higher than in solid

HEAT IS SUPPLIED
COOLED

CHANGES OF THE STATE OF MATTER CAUSED BY THE
ABSORPTION AND THE RELEASE OF HEAT BASED ON
