Select the correct pairings of colloidal system and type.

  1. AFog: liquid dispersed in gas
  2. BSmoke: gas dispersed in solid
  3. CMilk: liquid dispersed in liquid
  4. DColoured glass: solid dispersed in solid

Answer: A, C, D

Fog is liquid in gas, milk is liquid in liquid and coloured glass (metal particles in glass) is solid in solid, so these three are correct. Smoke consists of solid particles dispersed in gas, not gas in solid, so that pairing is wrong.
