Question

Dusty wind is a _________ mixture, whereas clean air is a ______ mixture.

• A. heterogeneous
• B. homogeneous

Answer 1

• The mixture in which components are uniformly distributed and components are not visible to the naked eye is called a homogeneous mixture.
• Clean air is a homogeneous mixture because the components are not seen and it is uniformly distributed.
• The mixture in which components are not uniformly distributed and components are visible to the naked eye is called a heterogeneous mixture.
• The dusty wind is a heterogeneous mixture because the components are seen and not uniformly distributed.

Therefore, the dusty wind is a heterogeneous mixture, whereas clean air is a homogeneous mixture.
