Sies Of Particles And Their Properties Flashcards
1
Q
Nano scale
A
Can be placed into one of three categories according to their diameter
- coarse particles
-fine particles
-nano particles
2
Q
Nano particles
A
Between 1-100 nanometers in size contain only a few 100 atoms. Much smaller than fine particles. Research into the production and application o them are called nanoscience.
3
Q
Very high surface to volume ratio
A
as the particles decrease in size surface area increases into relation to their volume.
4
Q
Course particles
A
Diameter 2500 and 10000m
Dust or PM 10
5
Q
Fine particles
A
Diameter 100 and 2500
PM2.5
6
Q
Nano particles diameter
A
diameter 1 and 100nm
7
Q
Nano particles are used for
A
Catalysis, titanium dioxide (has different particles in bulk and nano particle form)
