Properties of Matter IAN pg. 27
Slide 3
I. Matter has properties A. Physical Property: Characteristic
of a substance used to identify it including: Taste, Odor, Ductile,
Malleable, Volume, Color, Shape, Texture, Magnetic, Melting Point,
Boiling Point, Freezing Point Density,
Slide 4
1. Density is the amount of mass a substance has in a given
volume. (Physical Property) a. Formula(s) Include in your glossary!
M VD X SO 1. D = M/V 2. M = DxV 3. V = M/D
Slide 5
Remember You have to love Density Density = But It will break
your heart Density = Density = M v
Slide 6
Top IAN PAGE 26 DENSITY CALCULATIONS
Slide 7
1. EX. A 5 cm 3 glass of water weighs 13 grams. What is its
density? 13 grams. What is its density? D=m/v D= 13g/5cm 3 D= 2.6
g/cm 3 (Step 1) (Step 2) (Step 3) 2. EX. A 13 gram glass of water
has a density of 2.6 g/cm 3. What is its density of 2.6 g/cm 3.
What is its volume? volume? V=M/D V=13 g/2.6g/cm 3 V=5 cm 3
Slide 8
3. EX. A glass of water has a density of 2.6 g/cm 3 and a
volume of of 2.6 g/cm 3 and a volume of 5 cm 3. What is its mass? 5
cm 3. What is its mass? M=DVM=2.6g/cm 3 x 5 cm 3 M=13 g
Slide 9
2. Physical Change: A change that does not alter the identity
of a substance. a. What you start with is what you end with! what
you end with! EX. Ice (Solid) Water (Liquid) H 2 O H 2 O Breaking a
stick Tearing a Piece of Paper
Slide 10
3. Changes in state/phase of matter are physical changes.
Slide 11
I. Chemical Properties & Changes A. Chemical Properties
Describes how substances can form new substances Including:
Combustibility (How well it burns), Oxidation (Rusting,
Tarnishing), Reactivity, pH (Percent H + )
Slide 12
B. Chemical Change: Changing one substance into another
substance by rearranging atoms to form something NEW! NEW! 1.
Evidence of chemical change: bubbles, odor, color change,
temperature change, solid forms = Precipitate Ex. Burning, Rusting,
Digestion, Cooking
