Chem - Gases

Question 1

Kinetic Molecular Theory Postulate 1

Answer 1

Gas particles are tiny with large spaces between them

Question 2

Kinetic Molecular Theory Postulate 2

Answer 2

Gas particles are in constant, random, straight line motion except when they collide

Question 3

Kinetic Molecular Theory Postulate 3

Answer 3

Collisions are eleastic, and between collisions, molecules do not influence each other by attractive or repulsive forces

Question 4

Ideal gas

Answer 4

Hypothetical gas that exhibits a linear relationship among variables

Question 5

Question 12

Partial Pressure

Answer 12

The pressure exerted by each gas in a mixture

Question 13
