In the mixtures, the substances combined do not combine chemically, they combine only physically.
00:19
Therefore, all the components of a mixture retain their physical properties.
00:26
Now, on the basis of the particle size, a mixture can be classified as solution, colloids and suspension.
00:40
In solution, the particle size is less than 1 nanometer.
00:46
In this, the components cannot be separated using the method of centrifugation or decantation.
00:51
Its example is air.
