Chapter 5 - Gases Flashcards
Physical characteristics of gas
- assume volume and shape of their containers
- will mix evenly and completely when confined in the same container
- gases have much lower density than liquids and solids
Formula for force
Mass x acceleration
1 atm is equal to how many torr
760 torr
1 pascal equals
1 N/m^2
How to find pressure in atmospheres when given mmHg
Divide by 760 mmHg
1 atm and 760 mmHG equals this much kPa
1.01325 x 10^5
Temperature must be in what measurement
Kelvin
Celsius to kelvin
Celsius plus 273
Fahrenheit to kelvin
(Fahrenheit - 32) x 5/9
Ideal gas equation
P = nRT/V
760 torr equals
760 mmHg
Two formulas for Boyles law
P x V = Constant
P1 x V1 = P2 x V2
How many liters does 1 mole of gas occupy
22.41 L
Standard temperature of ideal gas
273 Kelvin (all temps should be in Kelvin)
What does “R” equal
.082057 Liters x atm/mol x K
Pressure formula
MolesxRxTemp in Kelvin/Volume
Before and after pressure formula
P1 x V1 / n1 x T1 = P2 x V2/n2 x T2
Density formula
m/V = P x M / R x T
m = mass in grams M = Molar mass of gas
Molar mass of gas formula
M = d x R x T / P
Gas diffusion
Gradual mixing of gases by virtue of their kinetic properties
Gas effusion
Gas under pressure escapes from one compartment of a container to another by passing through a small opening
Convert torr to atm
Divide torr given by 760 torr to get pressure in atm
Pressure should be converted to…
Atm always
Convert torr to atm
Divide torr given by 760 torr to get pressure in atm
