Chapter 14 - The Behavior Of Gasses

Question 0

Why are gasses easier to compress than solids or liquids?

Answer 0

Gases are easily compressed because of the spaces between the particles in a gas.

Question 1

Compressibility

Answer 1

A measure of how much the volume of matter decreases under pressure.

Question 2

What are the three factors that affect gas pressure?

Answer 2

The amount if gas, the volume, and the temperature are factors that affect gas pressure.

Question 3

Ideal gas law

Answer 3

PV=nRT.

Question 4

Under what conditions are real gases most likely to differ from ideal gases?

Answer 4

Real gases differ most from ideal gases at low temperatures and high pressures.

Question 5

Partial pressure

Answer 5

The contribution each gas in a mixture makes to the total pressure.

Question 6

Dalton’s law of partial pressures

Answer 6

At constant volume and temperature, the total pressure exerted by a mixture of gases is equal to the sum of partial pressures of the component gases.

Question 7

Diffusion

Answer 7

The tendency of molecules to move toward areas of lower concentration until the concentration is uniform throughout.

Question 8

Effusion

Answer 8

A gas escapes through a tiny hole in its container.

Question 9

Graham’s law of effusion

Answer 9

The rate of effusion of a gas is inversely proportional to the square root of the gas’s molar mass.
