Chapter 8: States of Matter

Question 1

Solid

Answer 1

A definite shape. the shape of a solid never changes unless acted on by an outside force

Question 2

Liquid

Answer 2

A definite volume. no matter the container or position of the object its length width and height never changes unless acted on by an outside force

Question 3

Gas

Answer 3

A changeable shape. A gas takes the shape of whatever container it is found in.

Question 4

Plasma

Answer 4

Large amount of thermal energy. when added to matter a decrease I thermal energy. when matter added to plasma a large increase in thermal energy.

Question 5

Crystalline Solids

Answer 5

Solids with regular patterns form crystals.

Question 6

Amorphous Solids

Answer 6

Solids without regular repeating patterns.

Question 7

Surface Tension

Answer 7

Molecules of a liquid are always pulling inward. This brings the molecules of the surface close together.

Question 8

Viscosity

Answer 8

A liquids resistance to flowing

Question 9

Fluids

Answer 9

A substance that flows

Question 10

Liquefaction

Answer 10

The change from a solid to a liquid

Question 11

Solidification

Answer 11

The change from a liquid to a solid

Question 12

Vaporization

Answer 12

The change from liquid to gas

Question 13

Sublimation

Answer 13

When particles of a solid gain energy and form gas

Question 14

Pressure

Answer 14

Gas particles constantly collide with one another and with the walls of the container they’re in

Question 15

Temperature

Answer 15

a measure of the average energy of random motion of particles in a substance

Question 16

Volume

Answer 16

The amount of matter in a given space

Question 17

Dependent Variable

Answer 17

that depends on other factors

Question 18

Independent Variable

Answer 18

It is a variable that stands alone and isn’t changed by the other variables you are trying to measure.

Question 19

Inversely Proportional

Answer 19

When the value of one quantity increases with respect to decrease in other or vice-versa

Question 20

Directly Proportional

Answer 20

if one quantity goes up by a certain percentage, the other quantity goes up by the same percentage as well.

Question 21

How does thermal temperature change States of matter?

Answer 21

Solid to liquid.
Increase in thermal energy.
Solid to gas.
Increase in thermal energy.
Liquid to gas.
Increase in thermal energy.
Gas to solid.
Decrease in thermal energy.
Gas to liquid.
Decrease in thermal energy.
Liquid to solid.
Decrease in thermal energy.

Question 22

particle arrangement in Solids liquids and gases

Answer 22

Solid - closely packed together
Liquid - loosely packed
Gas - very far apart

Question 23

Differences between melting and freezing points.

Answer 23

freezing- At this point the molecules in water begin to move slower and slower, forming regular patterns.
melting - Many scientists will compare melting points of substances to identify an unknown substance.

Question 24

Condensation

Answer 24

Particles in a gas lose enough thermal energy to form a liquid.

Question 25

how to calculate P or pressure

Answer 25

P = F\a

Question 26

Boyle’s law

Answer 26

Describes the relation between pressure and volume.

Question 27

Boiling point

Answer 27

Temperature in which a liquid boils
