Question

find and explain different activities to demonstrat

(a) diffusion of a liquid in another liquid
(b) diffusion of a solid in a liquid
(c) diffusion of a gas in a liquid​

Answer 1

a) Two factors which determine the rate of diffusion of a liquid in another liquid are: Temperature – higher is the temperature, greater is the rate of diffusion. Density- More is the density of one liquid, lesser is the rate of its diffusion in other liquid.

b) If a solid is kept in contact with excess of solvent in which it is soluble, some portion of the solid gets dissolved. This process is known as dissolution of a solid in liquid, and it takes place due to the diffusion of solid particles into liquid medium.

c)Molecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles.

Answer 2

It is non terminating and repeating decimal. for a no. To end with zero it should be in the form of2^n and 5^m but in this digit 3 ...
