Back (Answer)

The 4 quantities that describe the state of a gas: • Pressure • Temperature • Volume • Number of moles

#2
Front (Question)

STP =

Back (Answer)

Standard temperature and pressure

#3
Front (Question)

Standard temperature =

Back (Answer)

273 K (0 degrees Celsius)

#4
Front (Question)

Standard pressure =

Back (Answer)

1 atm = 760 mm Hg

#5
Front (Question)

Standard molar volume—At STP, one mole of (an ideal) gas has a volume of ___

Back (Answer)

22.414 L (new books may list 22.7 L)

#6
Front (Question)

3 empirical gas laws:

Back (Answer)

• Boyle’s Law • Charles’s Law • Avogadro’s Law

#7
Front (Question)

Boyle’s Law =

Back (Answer)

P1V1 = P2V2 Volume is inversely related to pressure (at constant n and T)

#8
Front (Question)

Charles’s Law =

Back (Answer)

V1/T1 = V2/T2 Volume is directly proportional to the absolute temperature (constant n and P)

#9
Front (Question)

Avogadro’s Law =

Back (Answer)

The volume of a gas is directly proportional to the number of gas molecules (constant T and P)

#10
Front (Question)

Boyle’s Law = ___ relationship

Back (Answer)

Volume-Pressure relationship
