Chapter 14- Gases Flashcards
1
Q
Boyle’s Law
A
- the volume of a fixed amount of gas at a constant temp varies inversely with pressure
- P1xV1=P2xV2
2
Q
Charles’s Law
A
- that the volume of a given amount of gas is directly proportional to its Kelvin temp at constant pressure
- V1/T1=V2/T2
3
Q
Gay-Lussac’s Law
A
- the pressure of a fixed amount of gas varies directly with the Kelvin temp when the volume remains constant
- P1/T1=P2/T2
4
Q
Combined Gas Law
A
the relationship among pressure, temp, and volume of a fixed amount of gas
P1xV1/T1=P2xV2/T2
5
Q
Standard Temp+Pressure
A
temp=273k
Pressure=1atm=760mm Hg=101.3kPa
6
Q
Ideal Gas Law
A
- PV=nRT
- relatesthe number of particles to pressure, temp, and volume
7
Q
Dalton’s Law of Partial Pressure
A
-Ptotal=P1+P2+P3
