Q.
How many types of nucleation process are there and what are they?
Answer & Explanation
Nucleation refers to the process where new phases or structures form in a material, typically in materials like metals or liquids. There are two main types- Homogeneous nucleation and Heterogeneous nucleation. In homogeneous nucleation, new phase formation occurs uniformly throughout the material. In contrast, heterogeneous nucleation happens on surfaces or impurities within the material. Understanding these processes is important in fields like material science and engineering, as they significantly influence properties like strength and thermal conductivity.
Thus correct option is: B.
