When perfume is spilt in one corner of the room, the fragnance spreads allover Why? Explain in diffusion terms

Answer 1

a solute moves from a high concentration to a low concentration. The fumes diffuse through the air in attempts to freely flow from that one corner to the surrounding areas where there is less volume of the fumes.

Answer 2

The term Brownian motion (in honor of the botanist Robert Brown) refers to either

1. The physical phenomenon that minute particles, immersed in a fluid, move about randomly; or
2. The mathematical models used to describe those random movements.

The mathematical model can also be used to describe many phenomena not resembling (other than mathematically) the random movements of minute particles. An often quoted example is stock market fluctuations. Another example is the evolution of physical characteristics in the fossil record.

Brownian motion is among the simplest stochastic processes on a continuous domain, and it is a limit of both simpler (see random walk) and more complicated stochastic processes. This universality is closely related to the universality of the normal distribution. In both cases, it is often mathematical convenience rather than accuracy as models that motivates their use. All three quoted examples of Brownian motion are cases of this:

1. It has been argued that Lévy flights are a more accurate, if still imperfect, model of stock-market fluctuations.
2. The physical Brownian motion can be modelled more accurately by a more general diffusion process.
3. The dust has not yet settled on what the best model for the fossil record is, even after correcting for non-Gaussian data

Answer 3

simply it's diffusion. any given solution wants to be isontonic. this basically means the same concentration througout. so when a perfume container is opened, that area of the room has a high concentration of 'perfume scent' to air. so the perfume scent spreads out so that there is an equal spread throughout the room. thus you open a bottle of perfume and soon you can smell it on the other side of the room. similar phenomenom when you put a drop of dye in water. over night the dye will spread out evenly through the water without stirring.

Answer 4

due to the diffusion of the molecules of the gas the fragance spreads all over the room .diffusion is the movement of molecules to the region of low concentration from the high concentration region .Thus the room which has low concentartion of the molecules of perfume shows the movement of molecule in the atmosphere & hence fragnance spreads.

Answer 5

The Brownian movement will spread molecules or atoms within fluids.
