CHAPTER 3 MATTER

THE BIG DOG

• The big dog is density
• The way to measure density is d=m/v
• The density of water is 1gram per cubic centimeter

PHYSICAL PROPERTY

• This is a property were it is easy to undo
• Some good examples are water
• Water in room tempature is water
• But at freezing is ice
• And at boiling is steam

CHEMICAL PROPERTY

• Is a process were it can not be undone
• An example is with baking soda and viniger
• The vinegar reacts with the baking soda releasing CO2

KEY CHEMICAL REACTIONS

• Fizzing
• Light
• Change in color
• Change in aroma

MASS VS VOLUME

• Volume is how mutch space somthing takes up
• volume is measured in cm3 or length
• mass is how heavy something is

VOLUME

• Volume is the size
• It is measured by L*H*W
• Volume can be meshured by a ruler
• And displacement
• Displacement is a object in a gratuaded cylender

GRATUATED CYLINDER

• You take the volume of the water
• And subtract by the end volume of the object
• And you get volume in mL
• And 1cm= 1mL
