Section 5.3- The Gas Laws

Question 1

the first careful research about the relationship between volume and pressure was done in the 1660s by

Answer 1

Robert Boyle

Question 2

says that at constant temperature for a given amount of gas, volume varies inversely with pressure

Answer 2

Boyle’s law

Question 3

equation for Boyle’s law

Answer 3

V= k* 1/P or PV=k

Question 4

Boyle’s law can also be stated in another way using just pressure and volume

Answer 4

P1V1=P2V2

Question 5

studied the effect of temperature on the volume of gas

Answer 5

Jacques Charles

Question 6

when working with relationships between temperature and volume, you must convert ___________ temperature to an _______________

Answer 6

Celsius
absolute scale

Question 7

states that the volume of a given amount of a gas at constant pressure is directly proportional to the absolute temperature

Answer 7

Charle’s Law

Question 8

equation for Charle’s law

Answer 8

V= kT or V/T=k or V1/T1=V2/T2

Question 9

Charle’s law only applies to

Answer 9

gases

Question 10

held constant with Boyle’s law

Answer 10

temperature

Question 11

constant in Charle’s law

Answer 11

pressure

Question 12

combined gas law (combo of Boyle’s law and Charle’s law) (neither pressure or temp held k)

Answer 12

PV/T = K
or
P1V1/T1= P2V2/T2

Question 13

is defined as 0 C and 1 atm

Answer 13

standard temperature and pressure

Question 14

found that when gases reacted, their reacting volumes, measured at the same temperature and pressure, were in a ratio of small numbers

Answer 14

Gay-Lussac

Question 15

when measured at the same temperature and pressure, the ratios of the volumes of gases that react or that are formed as products are small whole numbers

Answer 15

Gay-Lussac’s law of combining volumes

Question 16

says that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules

Answer 16

Avogadro’s Law

Question 17

Avogadro’s law equation

Answer 17

V= kn (P.T constant)

V1/n1 = V2/n2

Question 18

the volume per mole of a gas under specified conditions is the

Answer 18

molar volume

Question 19

for gases that behave very close to ideal, the molar volume at STP is about

Answer 19

22.4 L/mol

Question 20

molar volume only applies to

Answer 20

gases at STP

Question 21

ideal gas law in its usual form

Answer 21

PV=nRT

Question 22

is known as the ideal gas constant or universal gas constant

Answer 22

R in the equation PV=nRT

Question 23

value for the universal gas constant

Answer 23

0.082 L x atm (K x mol)
