|
Dispersion forces |
They are the forces between atoms or non polar molecules |
Without charge |
|
|
Boyles law |
Pressure is inversely proportional to volume of temp and moles remain same |
Constant t and n . Isotherm graph |
|
|
Charles law |
Volume is directly proportional to absolute temp at constant pressure |
Constant p .isobar graph |
|
|
Van der waals equation |
P+ an2/v2 * v-nb |
A and b are constants |
|
|
Compressibility factor |
Z = pv/nrt |
|
|
|
Boyles point |
The temperature at which real gas obeys ideal gas laws |
|
|
|
Liquefaction of gases |
A gas can be liquefied by cooling or applying pressure or a combined effect of both |
|
|
|
Critical temperature |
The temperature at which the gas liquefies |
|
|
|
Critical volume |
The volume of one mole of gas at critical temp |
|
|
|
Critical pressure |
The pressure of a gas at its critical temp |
|
|
|
Vapour pressure |
Vapour pressure in state of equilibrium between liquid phase and vapour phase |
|
|
|
Boiling point |
The temp at which the vapour pressure of liquid is equal to the external pressure |
|
|
|
Surface tension |
Force per unit length perpendicular to the surface . nm-1 |
|
|
|
Viscosity |
It the measure of resistance to flow which arises due to internal friction between two layers of the liquid as they flow past one another |
F = na du\dz |
|
|
Coefficient of viscosity |
It the measure of viscosity |
Ns m -2 Greater the viscosity , more slowly the liquid flows . glass is highly viscous |
