• General Properties of Matter

2
Matter

• Anything that has mass and takes up space!

3
Properties of Matter

• General
• Mass
• Weight
• Volume
• Density

• Specific
• Color
• Odor
• Size
• Texture
• Etc.

4
Mass

• The amount of matter in an object

5
Mass

• Mass does not change unless stuff is added or
  taken away (location has no effect)
• Base unit grams
• (but we use kg more)

6
Inertia

• Def resistance of an object to change in its
  motion
• Objects with larger mass have more inertia

7
Weight

• Def measure of the pull of gravity on an object

8
Weight

• Changes according to certain conditions
• Location moon/Jupiter
• Eat more
• Unit Newton

9
Gravity

• The force of attraction between objects

10
Mass vs. Weight

• They are not the same!

11
Weight ltgt Mass

• Weight mass x 9.8
• Mass weight/9.8
• Weight Newtons (N)
• Mass Kilograms (kg)
• Pounds x 4.45 Newtons

12
Mass vs. Weight
13
Volume

• Def the amount of space an object takes up
• Base Unit liter
• 1 cm3 1 mL

14
Finding Volume

• Square l x w x h
• Liquid grad cyl.
• Irregular water displacement

15
Density

• Mass per unit volume
• Formula
• mass /volume
• Units g/mL or g/cm3

16
Water

• Density of water
• 1 g/mL
• Object lt 1g/mL
• then floats
• Object gt 1g/mL
• then sinks

17
Density

• Density of ice is
• .92 g/mL
• Density of water increases as
• Depth increases
• Temperature decreases
