Understanding the properties of matter allows people to make practical applications;
MOLECULAR STRUCTURE
Liquid
LOOSELY HELD
Molecules , atoms
Gases
Solid
Physical and Chemical changes
TAKES SHAPE OF THE CONTAINER
Practical applsications - cooking, cleaning, bakinge
FAR APART
DOES NOT TAKE SHAPE OF A CONTAINER
understanding properties will assist practical application
ClOSELY HELD
DOSENT TAKE SHAPE OF THE CONTAINER
types of mTTER
lIQUID
GAS
SOLID
Molecular spacing:
Solid - Tightly packed
Liquid - loosely packed
Gas - very loosely spaced
Application of heat can change physical properties
Practical Application
Butter Melting Experiment
Rain Cycle -Evaporation, Condensation and Precipitation.
Matters properties
Gas
Solid
Liquid
Changes of the state of matter
Solid to Liquid to Gas
Example: Put an ice cube in a pan to observe changes of matter
Physical and chemical properties changes from one state to another.
