Ideal Gas Equation Flashcards
1
Q
Developmental theory
A
- volume of gas depends on temperature and pressure as the particles are further apart than in solids and liquids
- volume and moles are directly proportional
2
Q
Avogadros law
A
Volume and moles directly proportional
3
Q
3 laws combined to form ideal gas equation
A
Avogadros law v ~ n
Charles law: v ~ t
Boyles law: v ~ 1/p
(~ meaning directly proportional instead of fish)
4
Q

A
pV=nRT
5
Q
Pressure units
A
Pa
KPa x 1000
Nm-2
6
Q
Volume units
A
m3
cm3 / 1000000
dm3 / 1000
7
Q
Temperature units
A
Kelvin, K
C + 273
8
Q
how can the ideal gas equation be used in to determine the relative molecular gas of
a volatile liquid.
A
The liquid is weighed and then heated to a known temperature above its
boiling point. The volume of the gas is measured and the pressure recorded.
