Physical And Chemical Properties And Changes

Front 1

Define physical property.

Back 1

Characteristic of a substance that can be observed without changing it into another substance

Front 2

Define chemical property.

Back 2

Characteristic of a substance that describes its ability to change into a different substance

Front 3

Name all of the physical properties.

Back 3

melting point, viscosity, solubility, hardness, state of matter, texture, ductility, thermal conductivity, magnetism, boiling point, electrical conductivity, odor, density, malleability, and luster

Front 4

Name all of the chemical properties.

Back 4

reactivity, radioactivity, oxidation, flammability, and pH

Front 5

What does melting point mean?

Back 5

The temperature at which a substance changes from its solid state to its liquid states through melting.

Front 6

What does viscostiy mean?

Back 6

The state of being thick, sticky, and semifluid in consistency due to internal friction

Front 7

What does solubility mean?

Back 7

The amount of a substance that will dissolve in a given amount of another substance

Front 8

What does hardness mean?

Back 8

How easy or difficult it is to scratch something

Front 9

What does state of matter mean?

Back 9

The different forms in which matter can exist

Front 10

What does texture mean?

Back 10

The feel, appearance, or consistency of a surface or substance

Front 11

What does ductility mean?

Back 11

a solid material’s ability to deform under tensile stress

Front 12

What does thermal conductivity mean?

Back 12

A measure of how well a material can conduct heat

Front 13

What does magnetism mean?

Back 13

The property of attracting certain metals

Front 14

What does boiling point mean?

Back 14

The temperature at which a substance changes from its liquid state to its gas state through boiling

Front 15

What does electrical conductivity mean?

Back 15

the measure of the amount of electrical current a material can carry

Front 16

What does odor mean?

Back 16

the property of a substance that activates the sense of smell

Front 17

What does density mean?

Back 17

A property of matter representing the mass per unit volume

Front 18

What does malleabilty mean?

Back 18

the quality of something that can be shaped into something else without breaking

Front 19

What does luster mean?

Back 19

the state or quality of shining by reflecting light

Front 20

What does reactivity mean?

Back 20

the degree to which a substance is reactive

Front 21

What does radioactivity mean?

Back 21

the emission of ionizing radiation or particles caused by the spontaneous disintegration of atomic nuclei

Front 22

What does oxidation mean?

Back 22

Any chemical reaction when a material gives up electrons, as when the material combines with oxygen

Front 23

What does flammability mean?

Back 23

the ability of a substance to burn or ignite, causing fire or combustion

Front 24

What does pH mean?

Back 24

a number between 0 and 14 that indicates if a chemical is an acid or a base

Front 25

Define physical change.

Back 25

A physical change is when the form of matter is antered but NOT transformed into another substance.

Front 26

Define chemical change.

Back 26

A chemical change is when substances react to produce something new.

Front 27

What 4 things are evidence of a chemical change?

Back 27

heat production (hot or cold), light production, gas production, and new substance formed

Front 28

What is the difference between a physical change and a chemical change?

Back 28

A chemical change cannot EASILY be reversed. A physical change can. A physical change does not involve a change in the substance's chemical identity.
