Chapter 3 States of Matter

Question 1

Solids

Answer 1

Fixed positions, definite shape and volume

Question 2

Liquid

Answer 2

Definite volume but change shape, particles in a liquid are closely packed but they move past one another

Question 3

Gas

Answer 3

Particles expand and fill in container and move rapidly

Question 4

Plasma

Answer 4

State of matter the begins as a gas and then becomes ionized

Question 5

Energy

Answer 5

Capacity to do work

Question 6

Thermal energy

Answer 6

Kinetic energy of a substance’s atom

Question 6

Evaporation

Answer 6

Change of substance from liquid to gas

Question 7

Sublimation

Answer 7

Process of a solid directly to a gas, an be reversed

Question 9

Condensation

Answer 9

Change from a gas to a liquid

Question 10

Crystalline solids

Answer 10

Orderly arrangement of atoms and molecules

Question 11

Surface tension

Answer 11

The force on the particles at the surface of a certain liquid that cause drops to form a spherical shape

Question 12

Kinetic energy

Answer 12

An energy of motion

Question 13

Heat

Answer 13

A transfer of energy that causes temperature to change which leads to a change in state

Question 14

Endothermic energy

Answer 14

Require energy

Ex. Melting

Question 15

Exothermic energy

Answer 15

Energy is releases form substance during a change

Ex. Like condensation and freezing

Question 16

Fluid

Answer 16

Non solid state of matter in which atoms or molecules are able to move freely past one another

Question 17

Buoyant force

Answer 17

The upward force forced on an object floating or in a fluid

Question 18

Pressure

Answer 18

The amount of force put upon per unit area of a surface

Question 19

Archimedes’ principle

Answer 19

The Principle that states that the buoyant force on an object in a fluid is an upward force equal to the weight of the volume of a fluid that an object displaces

Question 20

Pascal

Answer 20

The SI unit of pressure

PA

Question 21

Pascal’s principle

Answer 21

The principle that states that fluid in equilibrium or is equal to is contained in a vessel exerts pressure of equal intensity in all directions

Question 22

Viscosity

Answer 22

The resistance of a gas or liquid to flow

Question 23

Boyle’s law

Answer 23

The law that states that for a fixed amount of a certain gas at a constant temperature, the volume of gas will increase as the pressure decreases. The opposite occurs if the rules are reversed.

Question 24

Charles’s law

Answer 24

The law that states that as the pressure of a gas stay constant the volume of a gas increases so will the temperature

Question 25

Gay-Lussac’s Law

Answer 25

States that pressure of a gas at a constant volume is proportional to the absolute amount of temperature

Question 26

Amorphous solids

Answer 26

Composed of atoms or molecules not in a particular order
