Avogadro's Law - 🧠 ANSWER ✔✔equal volumes of gases at the same
temperature and pressure contain equal numbers of molecules
Boyle's Law - 🧠 ANSWER ✔✔Boyle's Law states that at constant
temperature and moles, pressure and volume are inversely proportional.
Mathematically this is written as: PV = PV
,Charles' Law - 🧠 ANSWER ✔✔the law that states that for a fixed amount of
gas at a constant pressure, the volume of the gas increases as the
temperature of the gas increases and the volume of the gas decreases as
the temperature of the gas decreases
Gay-Lussac's Law - 🧠 ANSWER ✔✔the pressure of a gas is directly
proportional to the Kelvin temperature if the volume is constant
Combined Gas Law - 🧠 ANSWER ✔✔the relationship between the
pressure, volume, and temperature of a fixed amount of gas
Ideal Gas Law - 🧠 ANSWER ✔✔PV=nRT
R=.0821
If 5.00 g of Gas A and 5.00 g of Gas B are mixed in the same container,
and the partial pressure of Gas B is determined to be twice that of Gas A,
what do we know about the gases? - 🧠 ANSWER ✔✔If Gas A has half the
partial pressure of Gas B, this indicates that there are fewer moles of it at
the same mass, and therefore Gas A has twice the molar mass of Gas B
mol fraction and partial pressure - 🧠 ANSWER ✔✔the formula for both
, Amonton's Law - 🧠 ANSWER ✔✔if the volume of a gas is held constant,
increasing the temperature of the gas increases its pressure.
Boyle's Law
in terms of KE - 🧠 ANSWER ✔✔Volume decreased, wall area decreased =
increased pressure
Avagadro's Law
in terms of KE - 🧠 ANSWER ✔✔Container pressure constant, more gas
molecules added = increased volume
Dalton's Law - 🧠 ANSWER ✔✔The total pressure of a mixture of gases is
the sum of the individual pressures (Ptotal=P1+P2+P3...)
The kinetic energy (KE) of a particle of mass (m) and speed (u) is given by
- 🧠 ANSWER ✔✔KE = 1/2 mu^2
The KE avg of a collection of gas molecules is also directly proportional to
the temperature of the gas and may be described by the equation - 🧠
ANSWER ✔✔KEavg = 3/2 RT
Kinetic Molecular Theory - 🧠 ANSWER ✔✔The Kinetic Molecular Theory
states:
