Question

Question:If we open a bottle of perfume, its smell spreads in the entire room within a short time due to the process of:
A.Evaporation
B.Sublimation
C.Diffusion
D.Decantation

Answer 1

Hint: When we open a bottle of perfume, the tiny droplets of the perfume are released in the air. Just right outside the nozzle of the bottle, the concentration of these particles is high.

Complete step by step answer:
Before we derive to any conclusions with respect to this question, let us first understand what each of these mentioned processes mean.
Evaporation: evaporation is a process in which a substance changes from its liquid state to its gaseous state without any external heat. Evaporation of liquids occurs at room temperature.
Sublimation: Sublimation is a process in which a solid substance is directly converted to its gaseous state without going through its liquid state.
Diffusion: Diffusion can be simply explained as a process in which there is a movement of a substance from a region of higher concentration, to a region of lower concentration.
Decantation: Decantation is a separation process which involves the separation of mixtures by the removal of a liquid layer that is free of a precipitate or the solids deposited from a solution.
When we open a bottle of perfume, the tiny droplets of the perfume are released in the air. Just right outside the nozzle of the bottle, the concentration of these particles is high. As these articles move throughout the room, their relative concentration decreases. This behaviour of the perfume particles can thus be explained the process of diffusion.

Hence, Option C is the correct option.

Note:
The concept of diffusion is widely used in many fields, including physics (particle diffusion), chemistry, biology, sociology, economics, and finance (diffusion of people, ideas, and price values).
