a. Fog b. Cheese

Answer 1

Fog

dispersed phase liquid.
Dispersed medium gas.


cheese.

Dispersed phase liquid.

Dispersed medium solid.

Answer 2

The dispersed phase in fog is liquid, and that in cheese is solid.

The dispersion medium in fog is gas and that in cheese is liquid.

• The substance dispersed in a dispersion system is called the dispersed phase, and the substance in which another substance is dispersed is called the dispersion medium.

a. Fog - In fog, the water droplets are dispersed in atmosphere.

• Therefore, the dispersed phase is liquid (water droplets), and the dispersion medium is gas (air).

b. Cheese - Cheese is made of fats dispersed in water.

• Therefore, the dispersed phase in cheese is solid (fat) and the dispersion medium is liquid (water).
