Question

If smoke particles are suspended in air, how would you expect them to change?

1) They will settle down to the ground
2) They will disperse and spread out
3) They will evaporate into the air
4) They will become heavier and sink

Answer 1

Smoke particles suspended in air are expected to disperse and spread out(option 2).

Step-by-step explanation:

If smoke particles are suspended in air, they would be expected to disperse and spread out rather than settling down to the ground, evaporating into the air, or becoming heavier and sinking(option 2).

In the provided information, examples such as fog, clouds, and smoke are given as particles dispersed in air. These particles remain suspended in the air due to factors like their size, temperature, and density.

In the case of smoke, the solid carbon particles are small and light enough that they can float in the air, and they are often seen spreading out and dispersing over a larger area.
