The curve at a liquids surface by which one measures the volume of the liquid

Question 4

Mass

Answer 4

the measure of the amount of matter in a object

Question 5

weight

Answer 5

the measure of the gravitational force exerted on an object

Question 6

physical property

Answer 6

a characteristic of substance that does not involve a chemical change (Ex. of physical property: density, color, and hardness)

Question 7

density

Answer 7

the amount of matter in a givin space or volume

Question 8

physical change

Answer 8

a change that affects one or more physical properties of a substance

Question 9

chemical properties

Answer 9

a property of matter that describes a substance’s ability to participate in a chemical reaction

Question 10

chemical change

Answer 10

a change that occurs when one or more substances change into entirely new substances with different properties

Question 11

thermal conductivity

Answer 11

the rate at which a substance transfers heat

Question 12

ductility

Answer 12

the ability of a substance to be pulled into a wire

Question 13

malleability

Answer 13

the ability of a substance to be rolled or pounded into thin sheets

Question 14

states of matter

Answer 14

physical forms in which a substance can exist

Question 15

solid

Answer 15

the state of matter in which the volume and shape of a substance are fixed (ex: a soccer ball)

Question 16

liquid

Answer 16

state of matter that has definite volume, but not a definite shape

Question 17

viscosity

Answer 17

the resistance of a gas or liquid to flow

Question 18

gas

Answer 18

a form of matter that does not have a definite shape or volume

Question 19

temperature

Answer 19

a measure of how hot or cold something is specifically how fast the particles in an object are moving

Question 20

pressure

Answer 20

the amount of force exerted per unit area of a surface

Question 21

change of state

Answer 21

the change of a substance form one physical state to another

Question 22

melting

Answer 22

the change of state in which a solid becomes a liquid by adding energy

Question 23

evaporation

Answer 23

the change of a substance from a liquid to a gas

Question 24

boiling

Answer 24

the change of a liquid to a gas, throughout a liquid

Question 25

condensation

Answer 25

the change of state from a gas to liquid

Question 26

plasma

Answer 26

a state of matter that resembles a gas but has certain properties that gases don’t have. (has an infident volume and a fixed shape and particles that are electrically charged.)

Question 27

freezing

Answer 27

change in state in which a liquid becomes a solid

Question 28

deposition

Answer 28

the change in state from a gas directly to a solid

Question 29

sublimation

Answer 29

the process in which a solid changes directly into a gas

Question 30

kinetic theory of matter

Answer 30

all matter is made of atoms or groups of atoms that are in constant motion which explains solids, liquids, and gases.
