The molecules of perfume are in a gaseous state and mixing with the molecules of air in the room. All of them undergo random motion at all times as a result of the internal ("heat") energy that they have absorbed. The molecules often bump into each other, which causes them to mix if they were not mixed previously. Just as air expands to fill all available space, so too do gases in a closed container mix until the mixture is homogenous. This is entropic pressure, a "force" whose existence cannot be proven directly but can be argued statistically. Because the motion of the molecules is entirely random, the probability of finding a given concentration of perfume in a given volume of air approaches an even distribution throughout the room as time goes on. If that explanation was not clear enough, a simple analogy may help. Think of a box that is sparsely filled with two different colors of marbles, with the two colors initially separated. Shake the box. If you keep shaking, the two colors will eventually mix until the separation is entirely destroyed and the distribution is even. This is the same thing that happens to perfume molecules that begin concentrated above the surface of a girl's skin; they gradually disperse until they fill the entire room.

Do large cells move across the cell membrane quickly?
A large cell will never move across an intact cell membrane.
What process allows you to smell perfume at a distance source?
Diffusion of the perfume in the air allows you to smell it at a distance source. Diffusion is the process by which the particles of a substance move from an area of higher concentration (the original source) to an area of lower concentration (everywhere else in the room).
What is the name of the process of the smell of perfume passing throughout a room?
Diffusion. Where particles move from an area of high concentration to an area of low concentration. For example if perfume is sprayed in one corner of a room, it will be smelt soon after in the opposite corner. It is a random, natural process that doesn't require energy.
What part of a keyboard is used to move the cursor quickly across the line to pre-set points?

What does it mean if your crush says he likes your perfume?
1. It might mean hes just trying to be nice, and really does think you smell good. 2. He likes you too, and is trying to make a move. 3. He/she is trying to give you a hint that this perfume suits you well.
How do perfumes get to your noses?
The chemicals in a perfume evaporate easily in the air so that we can smell them.The chemicals can also be smelt.pppppppppppppppppp
Does C02 move quickly across the cell membrane?
Yes, carbon dioxide tends to be freely permeable across cell membranes and can transit through rapidly.
Does perfume go bad?
When perfume "expires", a few things could happen. The smell could dissappear or become very weak. The smell could also intensify or turn bitter, rotten, or have a new edge to it (indicating that it has gone bad). The liqid perfume could begin to congeal or form clumps, too.
In what direction did the railroads help people move across the country?
They helped people to move west. This helped with the growth that was seen out west because people could get out there more quickly.
Does a comet have a speedy streak of light?
No; you may be thinking of a "meteor". A comet may have a long tail, but it does not APPEAR to move quickly across the sky.
Oxygen molecules enter a cell by diffusion which is?
Diffusion is the movement of molecules or ions from high concentrated medium to low concentrated medium due to the continuous free movement of molecules, simply it's like spraying some perfume , air diffusion makes perfume molecules to move so that you can smell it every where in the room..
How do smells move around a room?
smell spread through diffusion.for example when you take the cap off a bottle ,the smell spreads out.after few minutes the scent can be detected severl meters away.this is because perfume molecules have escaped and moved across room by colliding wuth each other.
