The table gives the diameters of four particles.
| Particle | Diameter |
|---|---|
| W | 4.0 × 10-8 m |
| X | 0.15 μm\mu\mathrm{m}μm |
| Y | 8 nm |
| Z | 5.0 × 10-10 m |
(1 m = 1 × 109 nm and 1 μm\mu\mathrm{m}μm = 1000 nm)
Which of the particles are nanoparticles?
Y and Z only
Y only
W, X and Y only
