Holt Chemistry Ch2

Front 1

matter

Back 1

anything that has mass and volume or

anything that has mass and takes up space


e.g., air and a balloon both have matter (mass and volume)

Front 2

volume

Back 2

the space an object occupies

a measure of the size of a body or region in 3-dimensional space

Front 3

three ways to measure volume

Back 3

1) V = lwh (e.g., book)

2) graduated cylinders (liquids)

3) container it can fill (gas)

Front 4

mass

Back 4

the quantity of matter contained in that object

a measure of the amount of matter in an object; a fundamental property of an object that is not affected by the forces that act on the object, such as the gravitational force

Front 5

Name two physical properties that characterize matter.

Back 5

Mass and volume

Front 6

How does mass differ from weight?

Back 6

Weight depends on gravity, while mass does not.

Mass measures the quantity of matter in an object [no matter where it is in the universe].

The weight of an object is the force produced by gravity acting on mass (the quantity of matter).

Front 7

weight

Back 7

the force produced by gravity acting on mass.

a measure of the gravitational force exerted on an object; its value can change with the location of the object in the universe.

Front 8

balance

Back 8

device used for measuring mass in a laboratory

Front 9

newtons

Back 9

the way scientists express forces

Front 10

unit

Back 10

a quantity adopted as a standard of measurement

e.g., milliliters

Front 11

quantity

Back 11

something that has magnitude, size, or amount

e.g., volume

Front 12

SI

Back 12

Systeme Internationale d'Unites

(length (meter), mass (kilogram), time (second), thermodynamic temperature (kelvin), amount of substance (mole), electric current (ampere), and luminous intensity (candela)

Front 13

conversion factor

Back 13

a ratio that is derived from the equality of two different units and that can be used to convert from one unit to the other

Front 14

derived unit

Back 14

Units that are derived by multiplying or dividing base units.

Front 15

1L =

Back 15

1000 mL = 1000 cm^3

Front 16

1mL =

Back 16

1 cm^3

Front 17

physical property

Back 17

a property that can be determined without changing the nature of the substance.

a characteristic of a substance that does not involve a chemical change, such as density, color, or hardness.

Front 18

The properties of a substance may be classified as:

Back 18

1) physical
2) chemical

Front 19

Describe table sugar (sucrose) using physical properties.

Back 19

1) color--white
2) state--solid
3) gritty texture
4) melting point
5) boiling point

EX air -- colorless

Front 20

Describe matter qualitatively

Back 20

heavy, light, rough, and smooth

color, texture descriptions

Front 21

Describe matter quantitatively

Back 21

with numbers

Front 22

density

Back 22

the ratio of the mass of a substance to the volume of the substance; often expressed as grams per cubic centimeter for solids and liquids and as grams per liter for gases

Front 23

density formula

Back 23

mass
density = --------
volume
