Nanomaterials possess
Question and options
Nanomaterials possess
- Very low surface to volume ratio
- A surface to volume ratio that falls as particle size falls
- Very high surface to volume ratio
- Same surface to volume ratio as the bulk material
Answer and explanation
Correct answer: C - Very high surface to volume ratio
Nanoparticles are so small that a large fraction of their atoms lie at the surface, giving a very high surface-to-volume ratio, far higher than the bulk material. The ratio rises, not falls, as particle size shrinks, because surface area scales with the square and volume with the cube of size.
