Liquefaction of Gases
Non-Ideal Behavior of Gases
Plasma State
Key Points:
The behavior of gas is delineate through four variables i.e. pressure, volume, temperature and its range of moles. The relationships b/w gas variables ar understand because the easy gas laws. Boyle’s law relates pressure of a gas with its volume, whereas Charles’s law relates gas volume with temperature. Avogadro’s law thinks about with volume and quantity of gas.
By combining the higher than mentioned 3 laws, a additional general equation regarding the behavior of gas is obtained PV=nRT. This equation is solved for anybody of the variables once values of others ar illustrious.
Dalton’s law of partial pressure is wont to calculate the partial pressure of gases.
The process of diffusion and effusion ar best understood by Graham’s law of diffusion.
Kinetic molecular theory of gases provides a theoretical basis for varied gas laws. With the assistance of this theory a relationship is established b/w average molecular kinetic enegrgy and kelvin temperature.
The real gases show ideal behavior below specific conditions. They become non-ideal at air mass and coldness.
Gases is liquified applying comfortable pressure however temperature ought to either be essential one or below it.
To calculate the pressure of volume of a true gas below the non-ideal conditions, various kinetic equation has been developed. this can be called the van der Waal’s equation.
The plasma, a forth state of female parent, include neutral particles, positive ions and negative negatron, ninety nine of the illustrious universe is within the plasma state.
