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: liquid in solid; M: liquid in liquid; S: solid in gas

Solution

Cheese is a gel (liquid dispersed in solid), milk is an emulsion (liquid fat in liquid water), and smoke is an aerosol (solid particles in gas). Hence: C liquid in solid; M liquid in liquid; S solid in gas.
