Question 6What is the dimensionality of nanowires?

What is the standard form for 1 nanometre?1 × 10-8 m0.1 × 10-8 m0.1 × 10-9 m1 × 10-9 m2What size are nanoparticles?100-1000 nmMore than 1000 nmLess than 1 nm1-100 nm3Why are only very small amounts of nanoparticles required in industry compared with other molecules?Because they are unreactiveBecause they have a very large surface area to volume ratioBecause they have a very small surface area to volume ratioBecause they are highly flammable4Why do some people have concerns about the use of nanoparticles in sunscreens?They are flammableThey may not be very effectiveThey may enter the bloodstream with unpredictable resultsThey are very expensive
