Kinetic Molecular Theory Of Matter

Question 1

Definition of Volume & Shape

Answer 1

Amount of space occupied by the substance/molecules.

Question 2

Definition of Density

Answer 2

How much “stuff” (matter) is contained in a given space/area.

Question 3

Definition of Compressibility

Answer 3

The change in volume of a matter from pressure change.

Question 4

Definition of Thermal Expansion

Answer 4

Change in volume in response to a temperature change.

Question 5

Volume/Shape of States of Matter

Answer 5

Solid: Definite Shape; Definite Volume
Liquid: Definite Volume; Indefinite Shape
Gas: Indefinite Shape; Indefinite Volume

Question 6

Density of States of Matter

Answer 6

Solid: High
Liquid High but LOWER than Solid
Gas: Low

Question 7

Compressibility of States of Matter

Answer 7

Solid: Small
Liquid: Small, but greater than Solid
Gas: Large

Question 8

Thermal Expansion of States of Matter

Answer 8

Solid: Very Small (0.01% per C)
Liquid: Small (0.10% per C)
Gas: Moderate (0.30% per C)

Question 9

First Statement of Kinetic Molecular Theory of Matter

Answer 9

Matter is composed of tiny particles (atoms, molecules, or ions) that have definite sizes that do not change.

Question 10

Second Statement of Kinetic Molecular Theory of Matter

Answer 10

Particles are in constant random motion, producing Kinetic Energy.

Question 11

Third Statement of Kinetic Molecular Theory of Matter

Answer 11

Particles interact with one another through attractions and repulsions, possessing Potential Energy.

Question 12

Fourth Statement of Kinetic Molecular Theory of Matter

Answer 12

The Kinetic Energy of Particles increase as Temperature increases.

Question 13

Fifth Statement of Kinetic Molecular Theory of Matter

Answer 13

Particles transfer energy to one another through elastic collisions.
