Among the colloids cheese (C), milk (M), and smoke (S), the correct combination of the dispersed phase and dispersion medium, respectively is: (1) C : liquid in solid ; M : liquid in liquid ; S : solid in gas (2) C : liquid in solid ; M : liquid in solid ; S : solid in gas (3) C : solid in liquid ; M : liquid in liquid ; S : gas in solid (4) C : solid in liquid ; M : solid in liquid ; S : solid in gas

1. C : liquid in solid ; M : liquid in liquid ; S : solid in gas
2. C : liquid in solid ; M : liquid in solid ; S : solid in gas
3. C : solid in liquid ; M : liquid in liquid ; S : gas in solid
4. C : solid in liquid ; M : solid in liquid ; S : solid in gas

Correct answer: C : solid in liquid ; M : liquid in liquid ; S : gas in solid

Solution

The correct option identifies cheese as a solid dispersed in liquid, which is accurate since cheese consists of curds suspended in whey. Milk is correctly classified as a liquid dispersed in another liquid, while smoke is a colloid where solid particles are dispersed in gas, aligning with the definitions of these colloidal systems.
