|
273
|
|

What is the formula for Boyle's Law?
|
P1 V1=P2 V2
|
|
|
What is the formula for Charles' Law?
|
V1 / T1 = V2 / T2
|
|
|
What is the formula for Gay-Lussac's Law?
|
P1 / T1 = P2 / T2
|
|
|
What's the formula for the combined gas law?
|
P1 V1 / T1 = P2 V2 / T2
|
|
|
What's the formula for Avagadro's Law?
|
N1 / V1 = N2 / V2
|
|
|
What's the formula for Dalton's Law?
|
Pt = P1 + P2 + P3. . .
|
|
|
What's the formula for the Ideal Gas Law?
|
PV = nRT
|
|
|
What's the formula for Graham's Law?
|
V1 / V2 = root MW 2 / root MW 1
|
|
|
What is implied by Boyle's Law
|
Pressure is indirectly proportional to volume
|
|
|
What is implied by Charles' Law?
|
Volume is proportional to kelvin temperature
|
|
|
What is implied by Gay-Lussac's Law?
|
Pressure is directly proportional to temperature
|
|
|
What is implied by Avagadro's Principle?
|
Equal volumes of gases have equal numbers of particles at the same conditions.
|
|
|
What is implied by Avagadro's Law?
|
Since all gases have equal numbers of particles at like conditions, even different gases have proportional volumes and numbers of particles.
|
|
|
What is implied by Dalton's Law?
|
In a mixture of gases, the total pressure is equal to the sum of all of the pressures of individual gases added together
|
|
|
What is implied by the ideal gas law?
|
It is possible to compare the information of two different gases using mole:mole.
|
|
|
What is implied by Graham's Law?
|
Volumes can be used to compare molecular weights.
Also, rate of fusion can be compared with it, as volume is related to rate of fusion. |
|
|
How does velocity relate to size?
|
The larger a molecule is, the less the velocity. (Just imagine a giant molecule having trouble even moving, while the same energy will propel a molecule with low mass a larger distance)
|
|
|
At STP, what is molar volume of a gas?
|
22.4 L per mole.
|
|
|
What is the difference between an ideal gas and an actual gas?
|
In theory, gases have no pull between each other, they perfectly transfer all of their energy freely, and individual particles have no mass. Everything has mass, so the last part is obviously just a simplification of math. And gases do have pull- it's just "ignorable" as far as math goes.
|
|
|
How does one exploit the differences between an ideal gas and a real gas?
|
Create a very low density or high pressure.
|
|
|
What equation do we use to "remove" water vapor from a gas?
|
Dalton's
|
|
|
What equation do we use to compare rates of effusions?
|
Graham's
|
|
|
STP is what volume?
|
1 Liter
|
|
|
STP is what pressure?
|
1 ATM
|
|
|
STP is what temperature?
|
273K
|
|
|
How do you condense a gas?
|
Lower the temperature and/or up the pressure.
|
|
|
What diffuses faster, a larger or a smaller gas?
|
A smaller one
|
|
|
What relation do density and temperature have?
|
They are inversely proportional.
|
|
|
What is the MeoW form of the Ideal gas law?
(This is a simplified form of the Ideal gas law, converted for Molecular Weight) |
MW=DRT/P
Because MW, which is supposed to seem like Meow, for cat, is equal to Drt over P. Cats always put dirt over their pee. |
|
|
According to kinetic-molecular theory, are the particles in solids in motion?
|
Yes, unless it's at absolute zero
|
|
|
What is pressure?
|
Force of molecules beating against the side of a container
|
|
|
Barometers measure
|
pressure
