|
|
Particles of the perfume will move by osmosis but remain most concentrated in the corner where they were sprayed
|
|
|
Particles of the perfume will diffuse until they are spread evenly through the room
|
|
|
The movement of the particles of the perfume will be limited so they will remain concentrated in the corner of the room
|
Detailed explanation-1: -Diffusion is the process of spreading of the gaseous molecule according to their kinetic energy. In this process, particles move from an area of high concentration to an area of low concentration. If the perfume is sprayed in one corner of a room, it will be smelt soon after in the opposite corner.
Detailed explanation-2: -What will happen if a spray of perfume is released into one corner of a room? Particles of the perfume will diffuse until they are spread evenly through the room. They will move by diffusion and not by osmosis.
Detailed explanation-3: -Diffusion: Perfume particles mix with the particles of air. Due to diffusion, the particles of smelly gas are free to move quickly in all directions. So, The fragrance of perfume spreads in a room.
Detailed explanation-4: -So they spread from an area of high concentration to an area of low concentration in the air around through the gaps between the molecules of air in the room. This process is known as diffusion.
Detailed explanation-5: -We know that molecules of gases in the air are at constant motion. So the particle travels from higher concentration level to lower concentration level and spreads across the room due to which the odour can be detected from the other side of the room. This process is called diffusion.
