## What could speed up the movement of perfume sprayed on one side of the room to the other side of the room?

Answer with Explanation: “Diffusion” could speed up the movement of perfume sprayed on one side of the room to the other side of the room. Once a perfume is sprayed, it contains gas particles that readily takes up the space in the room.

## How does the smell of perfume spread in a room?

Diffusion in gases When chemical substances such as perfume are let loose in a room, their particles mix with the particles of air. The particles of smelly gas are free to move quickly in all directions. They eventually spread through the whole room from an area of high concentration to an area of low concentration.

## How can the rate of diffusion change?

Mass of the molecules diffusing: Heavier molecules move more slowly; therefore, they diffuse more slowly. The reverse is true for lighter molecules. Temperature: Higher temperatures increase the energy and therefore the movement of the molecules, increasing the rate of diffusion.

## How does a change in concentration influence the diffusion of perfume?

Answer: Diffusion. Molecules are in constant motion and tend to move from regions where they are in higher concentration to regions where they are less concentrated. An example of diffusion in gases occurs when a bottle of perfume is opened at the front of a room.

## How does the diffusion rate change when the concentration of solute molecules decreases?

Extent of the concentration gradient: The greater the difference in concentration, the more rapid the diffusion. Lower temperatures decrease the energy of the molecules, thus decreasing the rate of diffusion. Solvent density: As the density of a solvent increases, the rate of diffusion decreases.

## What is the difference between dissolving and diffusion?

Diffusion is the passage of particles from an area of higher concentration to an area of lower concentration. Dissolving is the bombardment of a solvent (e.g. water) on solute molecules (something that can dissolve, like sugar) forcing them apart. The solute mixes with a solvent to form a solution.

## What happens first dissolving or diffusion?

There is a link between dissolving and diffusing the main difference is that dissolving involves the breaking of bonds like those that hold solid particles together. Once a solvent and a solute dissolve the particles mix together and then diffuse to form an even mixture of particles.

## Is dissolving sugar diffusion?

When we put sugar in water and stir it, the sugar will dissolve in the water. This is because of diffusion, as the sugar will move down a concentration gradient. This means that it will move from a high concentrated area to a region of lower concentration.

## Is Diffusion a chemical reaction?

With these results, diffusion in a region between fixed concentrations can be described exactly as a chemical reaction for any potential function in the region, made of any combination of high or low barriers or wells.
