Physics · Nanotechnology
Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R. Assertion A: Nanomaterials exhibit a very high surface area-to-volume ratio. Reason R: As the particle size of a material is reduced, the surface area increases for a fixed total volume of the material. The inter-particle voids and pores created by the structured material also contribute to this increased surface area. In the light of the above statements, choose the most appropriate answer:
