What is the difference between Nano materials and Bulk materials?

Explanation

The solids are made up of particles. Each of the particle has a definite number of atoms, which might differ from material to material. If the particle of a solid is of size less than 100 nm, it is said to be a .nano solid.
. When the particle size exceeds 100 nm, it is a ‘bulk solid.. It is to be noted that nano and bulk solids may be of the same chemical compositio
. For example, ZnO can be both in bulk and nano form.
• Though chemical composition is the same, nano form of the material shows strikingly different properties when compared to its bulk counterpart.
