Answer 1

Answer: Colloids exhibit Tyndall effect. Tobacco smoke is a colloid.

Correct option is 1) Tobacco smoke

Answer 2

Answer:  

Tobacco smoke exhibit Tyndall effect.

Explanation:

‘Tyndall effect’ is a property exhibited by colloids. Colloids have their solute concentration smaller than suspension but ‘bigger’ than that of pure solutions. The other fall under pure solutions because they have smaller solute sizes.  

Tyndall effect can be defined as the scattering of light ray when the light ray are incident on an object and are dispersed by the solute particles of the medium. Colloids also exhibit ‘Brownian movement’ as it's property.
