GASEOUS STATE

GASEOUS STATE

The gaseous has the motion where they travelled without any barrier. they behave like 'AWARA'

Fig-  Random motion of the state of matter.

The gaseous state is based on the 2 main conditions where the combination of the gas law.

First Equation is for IDEAL GAS 

 PV=nRT

This equation is based on the combination of all the gas law.

A.B.C. 

Avogadro's Law

Boyle's Law

Charle's Law

(Alphabetical order)

Avogadro's Law- V ∝ n (P,T= constant)

Boyle'S Law-     V ∝1/P (n,T= constant)

Charle's Law-       V ∝ T(n,P= constant)

(Take the n, T & P in alphabetical order.)

IMPORTANT GRAPH OF GASEOUS LAW

BOYLE'S LAW

CHARLE'S LAW

Gay Lussac's Law 

Where the relation is about pressure and temperature.

P ∝T

PV=nRT
T-Temperature
P-Pressure
V-Volume
n-number of moles
R-Gas constant

Dalton's Law of partial pressure- 

This law is based on non-reacting gases. 

Addition of Partial pressure( individual pressure)of all non-reacting gases= Total Pressure of gases(Pₒ)

Pₒ=P₁+P₂+P₃

"Partial pressure in terms of mole fraction"

𝛘₁₌n₁/nₒ

 𝛘₁=P₁/Pₒ
------------
𝛘₁= Mole fraction
P₁= Partial pressure of Gas 1
Pₒ= Total pressure of Gas
n₁= moles of 1
nₒ= total no. of moles

Graham's Law of  Diffusion-
At constant T and P, the rate of diffusion is inversely proportional to the √density

Rate ∝ 1/ √d


The rate for two different gases.

r=v/t


Rate =Volume of the gas diffused /Time taken to the gas diffused 

r₁=v₁/t₁        for Gas 1  &
r₂=v₂/t₂         for Gas 2
