Chapter 14

Question 1

Gay-Lussac’s law

Answer 1

The pressure of a gas is directly proportional to the Kelvin temperature if the volume remains constant

Question 2

Ideal gas constant

Answer 2

Designated as R, this has the value of 8.31 (L×kPa)/(K×mol)

Question 3

Ideal gas law

Answer 3

Gas law that contains four variables and a constant P V T n R and describes the behavior of gasses

Question 4

Charles’s Law

Answer 4

The volume of a fixed mass of gas is directly proportional to the Kelvin temperature if the pressure is kept constant

Question 5

Compressibility

Answer 5

Measure of how much the volume of a matter decreases under pressure

Question 6

Boyle’s Law

Answer 6

For a given mass of a gas at a constant temperature, the volume of the gas varies inversely with pressure

Question 7

Combined gas law

Answer 7

The equation describes the relationship among pressure, volume and temperature of an enclosed gas

Question 8

Partial pressure

Answer 8

The contribution each gas in a mixture of gasses make to the total pressure

Question 9

Diffusion

Answer 9

Is the tendency of molecules to move towards areas of lower concentration until the concentration is uniform throughout

Question 10

Graham’s Law of Effusion

Answer 10

The rate of effusion of a gas is inversely proportional to the square root of a gas’s molar mass. The relationship is true for the diffusion of gases

Question 11

Dalton’s law of partial pressures

Answer 11

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

Question 12

Effusion

Answer 12

The process that occurs when gas escapes through a tiny hole in the container
