Physical & Chemical Changes : 

Physical & Chemical Changes

MATTER : 

MATTER Matter is anything which has mass & takes up space All matter is made of tiny particles called ATOMS

STATE OF MATTER : 

STATE OF MATTER There are 3 states of matter: solid, liquid, and gas

STATE OF MATTER : 

STATE OF MATTER SOLIDS Atoms held tightly together Has FIXED VOLUME & FIXED SHAPE

STATE OF MATTER : 

STATE OF MATTER LIQUIDS Atoms not held together as tightly Has FIXED VOLUME & SHAPE CHANGES according to container

STATE OF MATTER : 

STATE OF MATTER GASES Almost no force holding atoms together VOLUME CHANGES & SHAPE CHANGES according to container

Properties of Compounds : 

Properties of Compounds

PROPERTIES OF COMPOUNDS : 

PROPERTIES OF COMPOUNDS Compounds can be classified by their: PHYSICAL PROPERTIES Describes a compounds appearance Examples – color, texture, state of matter

PHYSICAL PROPERTIES (texture) : 

PHYSICAL PROPERTIES (texture)

PHYSICAL PROPERTIES (colour) : 

PHYSICAL PROPERTIES (colour)

PHYSICAL PROPERTIES (melting point) : 

PHYSICAL PROPERTIES (melting point)

PROPERTIES OF COMPOUNDS : 

PROPERTIES OF COMPOUNDS Compounds can be classified by their CHEMICAL PROPERTIES Describes a compounds behavior when mixed with other things Example – baking soda + vinegar

Physical Changes in Matter : 

Physical Changes in Matter

Physical Change : 

Physical Change Physical changes occur when matter changes its property but not its chemical nature.

Physical Change : 

Physical Change Physical property changes could include a change in: Texture, Shape, Size State of Matter Dissolving

Chemical Changes in Matter : 

Chemical Changes in Matter

CHEMICAL CHANGE : 

CHEMICAL CHANGE Chemical changes are changes matter undergoes when it becomes new substance or different matter. These “changes” are called chemical reactions

CHEMICAL CHANGE : 

CHEMICAL CHANGE A chemical change occurs when fireworks are used. Fireworks are made of metals such as magnesium and copper. These change chemically as they light up the sky.

FIREWORKS : 

FIREWORKS

CHEMICAL CHANGE : 

CHEMICAL CHANGE How do you know if there is a chemical change?

CHEMICAL CHANGE : 

CHEMICAL CHANGE Signs of a chemical change include: Changes in colour Formation of bubbles or a solid (called precipitate) Production of, heat, light or smoke
