are properties that are common to all forms of matter

Answer 1

mass and volume

Question 2

characteristics of matter that are present in all kinds of matter

Answer 2

general

properties of matter

Question 3

a property is observable only in a particular kind of matter

Answer 3

specific property of matte

Question 4

fundamental properties that are used to

describe matter are

Answer 4

mass, volume, weight, density, and specific gravity.

Question 5

refers to the amount of matter in an object

Answer 5

Mass

Question 6

Mass is usually expressed in

Answer 6

grams (g) or kilograms (kg).

Question 7

the measure of force that acts on an object

s expressed as the amount of
matter (mass) multiplied by the gravitational force that acts on it

Answer 7

weight

Question 8

Since weight is a force, it is expressed in

Answer 8

newtons (N)

Question 9

amount of space occupied by matter

Answer 9

volume

Question 10

Volumes of liquids are often expressed

in

Answer 10

milliliters (mL) or liters (L)

Question 11

Volumes of

solids are often expressed in

Answer 11

cubic centimeters (cm3) or cubic meters (m3).

Question 12

a physical property that expresses the ratio between
mass and volume

also tells how compact an object is

Answer 12

Density

Question 13

density is a ratio between mass and volume, it is often expressed in

Answer 13

kilograms per cubic meter (kg/m3
) or grams per cubic centimeter (g/cm3
).

Question 14

the ratio of a substance’s

density to a standard substance

Answer 14

Specific gravity

Question 15

also knowm as specific gravity

Answer 15

relative density

Question 16

Since specific gravity is a ratio
between two densities, it is a dimensionless
quantity wherein no physical dimension is
assigned.

Question 17

Qualities that are readily observable or measurable without changing the matter’s
composition

Answer 17

physical properties

Question 18

General properties such as mass, volume,

weight, density, and specific gravity are all examples of physical properties.

Question 19

As solids absorb heat
energy, its temperature increases, causing its particles to move faster and dissociate from
one another. This dissociation leads to a phase change known as

Answer 19

melting

Question 20

the temperature

at which a solid matter changes to liquid is known as

Answer 20

melting point

Question 21

The temperature at which a

liquid turns into a solid matter

Answer 21

freezing point

Question 22

or the change from a liquid state to a gaseous state

vapor

Answer 22

vaporization

Question 23

the

temperature at which liquid vaporizes

Answer 23

boiling point

Question 24

Materials that mix well form a homogeneous phase wherein the substance in a lesser
amount (solute) dissolves in another substance of greater amount (solvent)

Question 25

The ability of a | solute to dissolve in a given solvent

Answer 25

solubility

Question 26

A material is said to | be _ _ if it dissolves easily in a solvent.

Answer 26

highly soluble

Question 27

For the case of fluids like liquids and | gases, substances are said to be _ if they mix well together.

Answer 27

miscible

Question 28

Some substances that | do not completely mix are said to be

Answer 28

partially soluble or partially miscible

Question 29

a material that does not dissolve at all in a given solvent

Answer 29

insoluble or | immiscible

Answer 30

Metallic properties

Question 31

The ability of a material to allow heat or electric charges to pass through easily is known as

Answer 31

conductivity

Question 32

Metal can be flattened into thin sheets | due to its

Answer 32

malleability

Question 33

metal can be easily drawn | into wires due to its

Answer 33

ductility

Question 34

The characteristics that can only be seen when the chemical identity of a material is altered are known as

Answer 34

chemical properties

Question 35

The capacity of a material to decompose through the actions of microorganisms is known as

Answer 35

biodegradability.

Question 36

a chemical reaction between a substance (fuel) and oxygen which results in the generation of heat and light in the form of flame

Answer 36

combustion

Question 37

refers to the ability of a material to combust or burn

Answer 37

Combustibility

Question 38

the ability of a | combustible material to catch flame easily

Answer 38

flammability

Question 39

tendency of a substance to undergo a chemical reaction

Answer 39

reactivity

Question 40

elements that are known to have no to little reactivity

Answer 40

Question 41

Physical properties of matter may be further classified as intensive or extensive

Question 42

are physical properties that do not depend on the amount of matter

Answer 42

Intensive properties

Question 43

intensive properties are density, boiling point, melting point, and freezing point.

Question 44

are physical properties that depend on the amount of matter. These characteristics change when the amount of matter is decreased or increased.

Answer 44

Extensive properties

Question 45

Mass and | volume are extensive properties of matter.
