Gas law
law tht helps to define the relationship among pressure temperature mass and volume using these laws behaviour of gas under changing conditions can be predicted
Boyles law
Boyle’s Law states that:
“At constant temperature, the volume of a given mass of an ideal gas is inversely proportional to its pressure.”
Mathematically, this can be expressed as:
P1V1 = P2V2
Where:
- P1 and P2 are the initial and final pressures of the gas
- V1 and V2 are the initial and final volumes of the gas
In simpler terms, Boyle’s Law means that:
- If you increase the pressure of a gas, its volume will decrease
- If you decrease the pressure of a gas, its volume will increase
Charles law
At a constant pressure
Volume of gas is directly proportional to its temperature and vice versa
Gay lussacs law
In this assumes that volum is constant
Pressure and temperature are also directly proportional to one another
P/T=K
P1/T1=P2/T2
Ficks law
It describes diffusion process which is the movement of particles from a region of higher concentration to lower concentrations
Ficks first law applies to steady state diffusion where concentration doesn’t change with time
Ficks second law applies to non steady state diffusion where concentration changes with time
Henry’s law
States that amount of gas that dissolves in a liquid is directly proportional to partial pressure of that gas above the liquid assuming. Temperature is constant
C-concentration of gas in liquid
K constant
p partial pressure of gas above liquid.C=KP
Graham’s law
States that effusion of rate of gas is inversily propositional tothe square root of molar masses
r1-rate of effusion for gases
r2-rate ofeffusion of gase2
M1-molarmass of gas 1
m2 -molar mass of gas 2
r1/r1=m1/m2
Combined gas law
Combined gas law of 3 gases
Boyles law,Charles law,gaylussacs law
It states that ratio of product of pressure and volume and the absolute temperature of gas is equal to a constant
P1V1/T1=p2v2/t2
Daltons law
The pressure exerted by a single gas in a mixture is called it’s partial pressure
Daltons law describes the relationship between partial pressure and total pressure of a component
The principle states that partial pressure of gas must be proportional to its percentage in the mixture
Avagardros law
It states that volume of gas is directly related to the number of moles and gas
Tand P are constant
V1/n1=v2/n2
