Chapter 14- The Behavior of Gases

Question 1

compressibility

Answer 1

how much volume of matter decreases under pressure

Question 2

Boyle’s law

Answer 2

when the pressure of gas increases so does the volume

P1xV2= P2xV2

Question 3

Charles’s law

Answer 3

when the temperature increases so does the volume

V1/T2=V2/T2

Question 4

Gay- Lussac’s law

Answer 4

the pressure of gas is directly proportional to the Kelvin temperature
P1/T1=P2/T2

Question 5

combined gas law

Answer 5

the relationship between pressure, temperature and the volume of an enclosed gas.

Question 6

ideal gas law

Answer 6

PV=nRT

Pressure x Volume = moles of the contained gas x ideal gas consent x temperature

Question 7

ideal gas constant

Answer 7

R = 8.31

Question 8

partial pressure

Answer 8

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

Question 9

Dalton’s law of partial pressure

Answer 9

at constant volume and temperature, the total pressure made by a mixture of gases is equal to the sum of partial pressures of the separate gases.

Question 10

diffusion

Answer 10

molecules that tend to move areas of lower concentration until the concentration is even

Question 11

effusion

Answer 11

gas escapes through a tiny hole

Question 12

Graham’s law of effusion

Answer 12

the rate of effusion is inversely proportional to square root of the gases molar mass.
