Gas Laws Flashcards
How do particles in gas move?
They move very far apart and very fast.
How do gasses expand?
Gasses expand to fill any volume available to them.
Where does pressure come from?
Gas particles colliding with solid objects.
The pressure of gas is equal to what?
The frequency of collisions.
If the particles of gas increase in speed, what else will increase?
The temperature of the gas sample.
Is gas volume effected by outside changes in pressure and temperature?
Yes
What is Boyle’s Law?
Pressure and volume is inversely related. (PV=k)
What is Charles’ Law?
Temperature (K) and volume are directly related. (V/T=k)
What does k stand for?
Constant
What is a closed system?
The # of moles of a gas does not change.
How do you get Kelvin (K) from Celsius (C)?
273 + C = K
What does solubility represent?
The maximum amount of solute that can dissolve in 100 grams of solvent at a given temperature. (limit)
What kind of relationship does solubility of gas and temperature have?
Inverse relationship
What is Henry’s Law equation?
S1/P1=S2/P2
What is Concentrations?
How much solute is dissolved within an amount of solution. (quantitative)
What kind of property is dissolving?
A reversible, physical property.
What is Dilute?
A solution mostly of solvent with a small amount of solute.
What is a Concentrated solutions?
Solution has a lot of dissolved solute compared to the total amount of solution.
What is the universal gas constant?
0.0821 Latm/molK
What is the Ideal Gas Law equation?
PV = nRT (P=atm, V=L, n=#moles, T=K, R= gas constant)
What is a vacuum?
A space that does not contain any particles of matter.
What is Barometer?
An instrument that measures atmospheric pressure.
What is Dalton’s Law?
States that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases.
What is Atmospheric pressure?
The pressure we feel from the air around us.
What is standard pressure?
1 atm = 760 mmHg = 760 Torr
