4
Row 1, Col 1 How much space an object takes up… VOLUME
5
1,2 The basic particle of an element… ATOM
6
1,3 This is category of mixture is unevenly mixed and its individual parts can be seen… Ex. soup, salad, and salsa HETEROGENOUS
7
1,4 A characteristic of a substance that can be observed without changing it into another substance… Ex. Color, state, solubility, and melting point. PHYSCIAL PROPERTY
8
2,1 How much matter an object contains… MASS
9
2,2 A group of two or more atoms joined together by chemical bonds… Ex. H 2 O, table salt, sugar COMPOUND
10
2,3 Fog, butter, toothpaste, and paint are examples of this kind of mixture… COLLOID
11
2,4 Alters the form of substance but does not change it to a different substance… Ex. Evaporating, dissolving, and breaking PHYSCIAL CHANGE
12
3,1 The amount of mass per unit of volume… DENSITY
13
3,2 Simplest substances that cannot be broken down by chemical or physical means… Ex. Hydrogen (H), Oxygen (O), and Iron (Fe) ELEMENT
14
3,3 A type of mixture with large particles that settle… Can be easily separated… SUSPENSION
15
3,4 A substance’s ability to change into a different substance… Ex. Flammability, electrolysis, and rusting CHEMICAL PROPERTY
16
4,1 The formula for density… MASS DIVIDED BY VOLUME
17
4,2 Tells the elements and ratios of atoms in a compound… CHEMICAL FORMULA
18
4,3 A homogenous mixture in which one or more substances dissolve in another… SOLUTION
19
4,4 Produces one or more new substances through a chemical reaction… CHEMICAL CHANGE
20
5,1 The formula for slope… y 2 – y 1 x 2 – x 1
21
5,2 Made up of only one kind of matter and has definite properties… PURE SUBSTANCE
22
5,3 The scattering of light by particles in a mixture… Suspensions and colloids have this property… TYNDALL EFFECT
23
5,4 A type of change where energy is released… Ex. Burning paper and explosions EXOTHERMIC CHANGE

Final Jeopardy Question: An unknown substa nce has a de nsity of 7.87 g/cm 3 a nd mass of 15.74 grams what i s its volume? Will i t sink or float in water? Show ALL WORK on white board
25
VOLUME = MASS / DENSITY VOLUME = 15.74 g / 7.87 g/cm 3 VOLUME = 2 cm 3 SUBSTANCE WILL SINK IN WATER Final Jeopardy Answer:
26
Final Jeopardy Question: An unknown substance has a density of 0.85 g/cm 3 and volume of 3.38 cm 3 what is its mass? Will it sink or float in water? Show ALL WORK on white board
27
MASS = DENSITY x VOLUME MASS= 0.85 g/cm 3 x 3.38 cm 3 MASS = 2.873 g SUBSTANCE WILL FLOAT IN WATER Final Jeopardy Answer:
