2
New cards
What is Boyle’s Law?
In a gas, pressure and volu8me are inversely related when temperature is held constant
3
New cards
What is Charle’s Law Formula?
V1/T1 = V2/T2
4
New cards
What is Charles’ Law?
Volume(L or mL) and temperature (K) have a direct relationship at constant pressure
5
New cards
What is Gay Lussac’s Law Formula?
P1/T1 = P2/T2
6
New cards
What is Gay Lussac’s Law?
Pressure and Temperature are directly related when volume is held constant
7
New cards
What does the Combined Gas Law do?
States the relationship between pressure, volume, and temperature of a fixed amount of gas
8
New cards
What is the Combined Gas Law Formula?
P1V1/T1 = P2V2/T2
9
New cards
What is pressure?
measure of the force of a collision in a given area
10
New cards
What is volume?
measurement scientist use to determine the amount of space matter takes up
11
New cards
What is Molar volume?
the amount of volume or space that a mole of any gas at STP (0 degrees celsius and latm) would occupy
12
New cards
What are the conversions for pressure?
1 atm = 760 mmHg = 101kPa
13
New cards
What are the conversions for volume?
1 dm3 = 1L = 1000mL = 1000cm^3
14
New cards
What are the conversions for molar volume?
1 mol = 22.4
15
New cards
What is Temperature?
the average kinetic energy or movement of particles
16
New cards
What is the conversion for celsius to kelvin?
K = C + 273
17
New cards
What does the Ideal Gas Law describe?
the physical behavior of an ideal gas in terms of the pressure, volume, temperature, and number of moles of a gas present
18
New cards
What is the Ideal Gas Law Formula?
PV = nRT
19
New cards
What are the R constant value conversions for the Ideal Gas Law Formula?
8\.314 (kPa)(L) / (mol)(K) = 62.36 (mmHg)(L) / (mol)(K) = 0.00821 (atm)(L) / (mol)(K)

What is Dalton’s Law?
The total pressure of a mixture of gases is the sum of the partial pressures of the individual gases
21
New cards
What is the Dalton’s Law Equation?
Ptotal = P1 + P2 + P3 ….
22
New cards
What is Graham’s Law of Effusion?
The rate of effusion (or diffusion) of a gas is inversely related to its molar mass
23
New cards
What is Diffusion?
gas molecules spread from high concentration to low concentration.
24
New cards
What is Effusion?
gas molecules ability to pass through a small opening.
25
New cards
Lighter gases spread ____ than heavier gases
faster
26
New cards
What is Graham’s Law of Effusion formula?
Rate of effusion for gas 1/Rate of effusion for gas 2 = √MW2/√MW1
