Question

Explain with activity particles are extremely smaller in size

Answer 1

Answer:We can prove this by taking water, potassium permanganate [KMNO4] and 4 breakers.

Take the beakerA and put 2-3 small crystals of KMNO4 and put 100ml of water in the beaker.Take 90 ml of water in the beaker A, B, C each. Now take 10 ml of water from breaker A and put in beaker B it will look lighter than A. Repeat this process again with beaker C, it will look lighter than B. Again repeat it with Beaker D. After dilution it will look very lighter than A.

Since tiny crystal of KMNO4 is made up of millions of particles.

Hence these particles must be very -very small.
