Chapter 10

Question 1

Properties of Gases

Answer 1

• assume the shape and volume of its container
• can be compressed
• have lower densities
• form homogenous mixtures
• described by volume, amount, temp, pressure

Question 2

Kinetic Theory of Gases

Answer 2

• gas composed of large number of particles that seem like round objects that move in constant motion
• move in straight lines until they collide with another particle or the walls of a container

Question 3

Pressure

Answer 3

force applied per unit area
= Force/Area

Question 4

Boyle’s Law

Answer 4

P1V1 = P2V2
- used only at constant T and n

Question 5

Charles’s Law

Answer 5

V1/T1 = V2/T2
- used only with constant P and n

Question 6

Avogadro’s Law

Answer 6

1 mol (g) = 22.4 L
- used only with STP (1 atm and 0 deg C)

Question 7

Ideal Gas Law

Answer 7

PV = nRT
- R = gas constant = 0.08206 L x atm/mol x K

Question 8

What happens to the pressure if the volume of a container is decreased?

Answer 8

increased; P (proportionate) 1/v

Question 9

What happens to the pressure if we increase the temperature inside the container?

Answer 9

increased; P (proportionate) T

Question 10

STP

Answer 10

1 atm and 0 degrees C

Question 11

Avogadros number

Answer 11

6.0221e23

Question 12

Ideal gas laws assume

Answer 12

1. no attractions between gas molecules
2. gas molecules do not take up space
