what is the means of dielectric constant ?

-
Answer:-
Dielectric constant is a property of medium.
Dielectric constant of a medium is defined as the ratio of permitivity of that medium to the permitivity of free space.
Dielectric constant is also known as relative permitivity of the medium.this defination is only valid in C.G.S system.

It is denoted by. K  
I.e
what is the means of dielectric constant ?
As it is the ratio of two like quantities it is unitless and dimensionless.
More is the dielectric constant of the medium lesser is the Electrostatic force in that medium.
It depends only on the medium on which charges are placed.

Are you satisfied by this answer

What is Freundlich adsorption isotherm ?

-
Image
Explanation:- The variation in the amount of gas adsorbed by the adsorbent with pressure at constant temperature can be expressed by means of a curve termed as adsorption isotherm. According to freundlich isotherm,     The extent of adsorption of a gas per unit mass of adsorbent depends upon the pressure of that gas. I.e Look at the Graph,(x/m) vs (p) Equation (1) is the general form of freundlich adsorption isotherm. Case-1( at low pressure) If  x/m =kp¹ That implies 1/n=1 I.e  n=1 So at low pressure freundlich adsorption isotherm holds good because initially their is more adsorption occur. Case-2 (at high pressure) If x/m=constant  i.e1/n=0 That implies n=infinity So at high pressure x/m independent on pressure because after saturation pressure their is no adsorption occur due to no space on adsorbent. At saturation pressure Amount of gas adsorbed=amount of gas desorbed. Look at the logarithm graph of equation (1) This is all about freundlich adsor
