Www- talked about how it is closer at first then spreads and used

# data[].attributes.body
Very good explanation of diffusion and good use of keywords.

# data[].attributes.body
You have not included for when the deodorant has diffused completely. What will happen to it? Does it still smell strong? Etc. Good explanation on the high concentration at the start though.

# data[].attributes.headline
Check your letters because you said c will smell it very strongly and then later you said c might not even smell it.  What happens when the gas particles from the deodorant diffuses completely?

WWW: They identified the order correctly. Good job in explaining that person B will receive less gas particles than the others.

EBI: Maybe explain diffusion in more detail.

Www: you explained well how

The concentration works and when the

Gas diffuses.

EBI: explain what happens when they collide

With the air particles and how it could affect the concentration

• Agreed to the order.

WWW

- you said the particles move in a RANDOM MOTION

- mentioned DIFFUSION

- good description of deodorant particles mixing with air particles

EBI

- use the keyword "concentration"

- Elaborate on why the smell won't be as strong for B

ORDER- CAB

The deodaerant is very concentrated at the area where it is sprayed, it will then move slowly to a lower concentration are (where B is). The process of moving to the lower concentration area is called diffusion. As the gas diffuses, the particles spread out and reach C first then to A and finally B.

C,A,B. For C it will be quite strong, for A it will be less noticeable and for B it will be hardly noticeable. When the deodorant is sprayed it is very concentrated so person C will smell it when it is very concentrated. When the deoderants particles have spread out and diffused with the air particles in the room, the scent becomes less and less concentrated.

# data[].attributes.body
Order: CAB

because the particles will diffuse in all directions and the person

Who is closes will smell it first

Also c will smell it the most because when he smells it all the particles will still be closer and by the time b smells it the particles will be spread out more. Also it is a liquid to a gas. So when it starts the bonds just broke so they are closer together.

# data[].attributes.body
Order - CAB

The gas particles in the deodorant diffuse in all directions. As the gas particles were in a region of high concentration in the can, the particles diffuse very quickly when they are released into the air, a region of low concentration. So, the people standing nearest the corner will smell the deodorant first.

the gas particles are completely diffused when the particles eventually spread through the whole room.

# data[].attributes.body
The order is CAB because when it is sprayed The gas will diffuse in a random motion and as c is the closest it will reach c first and when it collides with air particles they will start to mix with the other air particles but the smell won't be as strong for the A and the smell will be even less for B.

Order: C,A,B

As the gas particles in the aerosol can are compressed, when it is released the particles are fairly close together in the corner. The can is sprayed, and over time the gas particles begin to disperse (or diffuse) into the air. The particles move throughout the room from the source, first reaching the people closest to the can.

Order:CAB

The deoderant from the corner will diffuse in all/random (brownian motion) directions of the room, and the closest person to the deoderant (C) will smell it first,then A then B. However, B might not smell it at all as the deoderant gas will be too thinly spread throughout the room. C will smell it very strongly as it is near the region of high concentration of the gas. From there it will diffuse very quickly as the particles collide alot until they reach the region of low concentration, then the diffusion will stop as the particles have reached equilibrium.

Diffusion is when a certain gas's particles bounce around along with another gas in random movements.
