Gas Laws Flashcards
1
Q
Charle’s Law
A
V1/T1=V2/T2
2
Q
Absolute Temp Scale proposed By and when?
What was his nickname?
A
William Thompson in 1848
Title was Lord Kelvin
0K= -273.15 c
3
Q
Avorgado’s Law (AL)
A
V1/n1= V2/n2
4
Q
Combined Gas Law
A
P1V1/T1=P2V2/T2
5
Q
Ideal (Perfect) Gas Law
A
PV=nRT
P- Pressure in atm V- Volume in liters (L) T- Temperature in kelvin n- # of moles of gas R- gas constant, 0.0821L*atm/mol*k (8.314g/mol*K)
6
Q
Dalton’s law of partial pressure
A
Ptotal= P1+P2+P3+….
Ptotal= (nRT/V)1+(nRT/V)2+(nRT/V)3+……
7
Q
Boyles’s laws (BL)
A
P1V1=P2V2
8
Q
Kinetic Energy (KE)
A
(T/2)mv^2
T- temp
m-mass (kg)
v-velocity (meters/second)
9
Q
Molecular weight of gas
A
PV=nRT
n- m/MW
so
PV=(m/MW)RT
10
Q
Density of a gas/ molar mass
A
d=(P*MW)/RT
MW- molecular weight
