it all builds up
The most basic answer would be that they dont have the same properties as the bulk material and these particles in the nm size range are governed by quantum mechanics.
If the particles in a substance are moving, the volume of that substance becomes larger because the particles move faster and spread farther appart. the mass of the object stays the same because it is the same amount of particles, just in a format in which the volume is larger. hope i helped :)

Quarks are considered to be fundamental particles, and as such they do not really have a classical "size". Their masses can be compared, however, and they are not the same for all types of quarks.
Sand particles are in fact a variety of sizes on the same beach front. This is because these sand particles are formed at different times through different processes.
round particles of the same size.
becuz the particles don't move
False! Not all chemical reactions take place at the same rate.
Liquids cannot stay the same size size because the particles inside the liquids have some bit of space to move to a different shape and to change the size.
Sometimes you can see them and sometimes not. It all depends what the particles are made of and their size.
Subatomic particles are the same size as basketballs.
Round particles of the same size, as in pure quartz sand.
