NCERT What are suspensions? Explain

with an example.

Answer: 

A suspension is a heterogeneous mixture in which very fine particles (about 10-5 m size) of solid are dispersed in any medium (liquid or gas). 

In suspension, the solute particles are visible to the naked eye, and remain suspended throughout the bulk of the medium. 

The Tyndall effect is observed in this mixture. Muddy pond water, smoke coming out of a chimney, chalk-water mixture, coarse lime particles in water

are examples of suspension.
