What is the difference between Nano materials and Bulk materials?

1.	What is the difference between Nano materials and Bulk materials?
Answer» 1. 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’. 2. 2.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 composition. 3. For example, ZnO can be both in bulk and nano form. 4. Though chemical composition is the same, nano form of the material shows strikingly different properties when compared to its bulk counterpart.
