Explanation: The ratio of the rates of diffusion of two gases is equal to the square root of the inverse of their molar masses.
Rate of Diffusion:
what factor influeneces it?
Explanation: Graham’s Law relates the speed at which gases diffuse, which is influenced by their molar masses.
Inverse Relationship:
Explanation: Graham’s Law
Explanation: Graham’s Law shows an inverse relationship between the rate of diffusion and the molar mass of a gas. Smaller molar mass, faster diffusion.
: Boyle’s Law
Definition: A fundamental principle in physics that describes the relationship between the volume and pressure of a gas when the temperature is held constant.
Boyle’s Law Equation:
Explanation: The product of the initial volume and pressure of a gas is equal to the product of the final volume and pressure, where “k” is a constant.
PV = k
According to Boyle’s Law, when the volume of a gas increases, its pressure ?
According to Boyle’s Law, when the volume of a gas increases, its pressure decreases, and vice versa, as long as the temperature remains constant.
: Boyle’s Law demonstrates an inverse relationship between pressure and ?
: Boyle’s Law demonstrates an inverse relationship between pressure and volume. If one increases, the other decreases, and vice versa.
Charles’s Law?
A gas law that describes the relationship between the volume and temperature of a gas when pressure is held constant.
Charles’s Law Equation:
Explanation: The ratio of the initial volume and temperature of a gas is equal to the ratio of the final volume and temperature, as long as pressure remains constant.
V1/T1 = V2/T2
Charles’s Law demonstrates that as the temperature of a gas increases, its volume?
Charles’s Law demonstrates that as the temperature of a gas increases, its volume also increases, and vice versa, when pressure is held constant.
Term: Avogadro’s Law?
Definition: A gas law that describes the relationship between the volume and the number of moles of a gas when pressure and temperature are held constant.
Avogadro’s Law Equation:
Explanation: The ratio of the initial volume and the initial number of moles of a gas is equal to the ratio of the final volume and the final number of moles, provided that pressure and temperature remain constant.
* V1/n1 = V2/n2*
Avogadro’s Law illustrates that as the number of moles of a gas increases, the volume of the gas?
Avogadro’s Law illustrates that as the number of moles of a gas increases, the volume of the gas also increases, and vice versa, as long as pressure and temperature are constant.
which gas law eq. shows a parabolic curve?
Boyles law
bc its has an inverse relationship
0K = F? C?
-273 C
-414F
which law do real gases don’t follow?
charles law
bc zero temp cannot give zero vloume bc at that temp gases becoems liquid anyways
on which conditions do real gase not follow the gas laws?
at high pressure and low temp
bc the vlomune is not nieiglbe
The ideal gas law fails at low temperature and high-pressure because the volume occupied by the gas is quite small, so the inter-molecular distance between the molecules decreases.
ideal gas assumstions?
The molecules exert no forces (attractive or repulsive) on one another except when they actually collide with each other and with a wall.
The molecules are like geometric mass-points, the actual volume occupied by them is negligible, compared to the total volume of the gas (container).
what Dalton’s Law of Partial Pressures
A gas law that states that the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of the individual gases.
Dalton’s Law Equation:
e total pressure (P_total) of a gas mixture is the sum of the partial pressures (P_1, P_2, P_3, etc.) of the individual gases in the mixture.
where does Mole Fraction come in daltons equation?
Explanation: The mole fraction of a gas in a mixture is the ratio of the number of moles of that gas to the total number of moles in the mixture. It is used to calculate partial pressures.
why is the rate of diffusion slower is liqids as compared t gases?
bc in liquids
the sloute molecule collides with the liquids molecules which slows down their speed so the diffuion slows down
what is vapour pressure
the pressure exerted by vapours at equiibrium state
