Question

Assertion (A): Dust particle in air form aerosol.
Reason (R) : Dust particles from dispersion medium and air is
dispersed phase. (a). Both A and R are true and R is the correct explaination of A (b). Both A and B are true and R is not the correct explanation of A. (c). A is true but R is false (d). A is false but R is true​ ​

Answer 1

Answer:

(b) Both A and B are true and R is correct explaination of A.

Answer 2

(a). Both A and R are true and R is the correct explanation of A is the correct option

Explanation:

Dust particle in air form aerosol:

• Dust particles in the atmosphere, also known as particulate matter (PM), come from a multitude of sources. Many particles attract water vapour in humid environments and develop to create tiny droplets.
• Both solid particles and droplets suspended in air are commonly referred to as "aerosols.

Dust particles from dispersion medium and air is dispersed phase:

• The dispersed phase is defined as a phase that is scattered or present in the form of colloidal particles. The dispersion media is the medium in which colloidal particles are distributed.
• Gas serves as the dispersion medium, while solid serves as the dispersed phase.
