Final answer:
Nanomaterials exhibit changes in properties like increased conductivity, altered optical properties, and enhanced mechanical strength due to quantum effects and increased surface area to volume ratio at the nanoscale.
Step-by-step explanation:
When a material is reduced to nanomaterials from its bulk form, several properties can change dramatically due to the quantum effects and large surface area to volume ratio at the nanoscale.
These changes in properties result from the distinct arrangement and interactions of atoms at the nanoscale and have significant implications for technology and material science.
