Question

Which is the most important property of nanomaterials?
A. Force
B. Friction
C. Pressure
D. Temperature

Answer 1

Scientists have not reached an agreement on a precise definition of nanomaterials, but they do agree that they are distinguished by their small size, measured in nanometers. A nanometer is one-millionth of a millimeter or 100,000 times smaller than the width of a human hair.

Complete answer:
In general, nanomaterials are materials with a single unit size ranging from 1 to 100 nm.Nanomaterials research approaches nanotechnology from a materials science perspective, leveraging advances in materials metrology and synthesis developed in support of microfabrication research.

The most important property of nano metals is friction. Nanomaterials are unique for several reasons, one of which is their small size. Nanomaterials can be up to ten thousand times smaller than the width of a human hair. The surface area to volume ratio of nanoparticles is extremely high.

Nanomaterials' distinct properties are attributed to quantum effects, larger surface area, and self-assembly. Quantum effects can begin to dominate matter's behavior at the nanoscale, particularly at the lower end, affecting materials' optical, electrical, and magnetic properties.Nanotechnology has the potential to enable new and faster computer types, more efficient power sources, and life-saving medical treatments. Economic disruption and potential threats to security, privacy, health, and the environment are among the potential drawbacks.

Hence, the correct answer is option B.

Note: Nanotechnology can be used to create pharmaceuticals that target specific organs or cells in the body, such as cancer cells, and thus improve therapy effectiveness. Nanomaterials can also be used to strengthen and lighten cement, cloth, and other materials.
