Chapter 3 States Of Matter

Question 1

Solid

Answer 1

Substances that are in a fixed position

Question 2

Liquid

Answer 2

Substance where the particular are close together but can slide past each other

Question 3

Gas

Answer 3

Particles are constantly moving and rarely stick together

Question 4

Plasma

Answer 4

A state of matter that starts as a gas and then becomes ionized

Question 5

Energy

Answer 5

The capacity to do work

Question 6

Thermal Energy

Answer 6

The kinetic energy of a substance’s atoms

Question 7

Evaporation

Answer 7

The change of a substance from a liquid to a gas

Question 8

Sublimation

Answer 8

The process where a solid changes directly into a gas (reverse process)

Question 9

Condensation

Answer 9

Where a substance changes from a gas to a liquid

Question 10

Crystalline Solid

Answer 10

Particles have an orderly arrangement

Question 11

Amorphous Solid

Answer 11

Particles do not have an orderly arrangement

Question 12

Surface Tension

Answer 12

A property of a liquids where the force acting on particles at the surface of a liquid can cause it to form drops

Question 13

Kinetic Energy

Answer 13

Energy of motion

Question 14

Heat

Answer 14

Causes the temperature of a substance to change, which can lead to a change of state

Question 15

Endothermic Change

Answer 15

Changes, like melting, that require energy

Question 16

Exothermic Change

Answer 16

Energy is released from the substance as it changes state

Question 17

Fluid

Answer 17

A nonsolid state of matter where the atoms or molecules are free to move past each other, like in a gas or liquid

Question 18

Buoyant Force

Answer 18

The upward force exerted on an object immersed in of floating on a liquid

Question 19

Pressure

Answer 19

The amount of force exerted per unit area of surface

Question 20

Archimedes’ Principle

Answer 20

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

Question 21

Pascal

Answer 21

SI Unit of pressure; equal to the force of 1 N exerted over an area of 1 m^2
(abbreviation, Pa)

Question 22

Pascal’s Principle

Answer 22

Principle that states that a fluid in equilibrium contained in a vessel exerts a pressure of equal intensity in all directions

Question 23

Viscosity

Answer 23

The resistance of a gas or liquid to flow

Question 24

Boyle’s Law

Answer 24

Law that states that for a fixed amount of gas at a constant temperature, the volume of the gas increases as the pressure decreases
As the volume decreases, the pressure increases

Question 25

Charle’s Law

Answer 25

Law that states that for a fixed amount of gas at a constant pressure, the volume increases as the temperature increases
As the volume decreases, the temperature decreases

Question 26

Gay-Lussac’s Law

Answer 26

Law that states that the pressure of a gas at a constant volume is directly the same to the absolute temperature
