Anisotropy in Snowflakes

Anisotropy refers to the property of a material that exhibits different physical properties in different directions. The following options were given:

a)Hair wax
b)Snowflakes
c)Polythene
d)Crystal glass

Out of these options, snowflakes possess anisotropic nature within their structure. This is because of their unique structure that is formed due to the freezing of water molecules.

Explanation:

The structure of snowflakes is formed due to the freezing of water molecules in the atmosphere. As the water molecules freeze, they arrange themselves in a crystalline structure that is six-sided. This hexagonal structure is formed due to the orientation of hydrogen bonds between the water molecules.

This orientation of hydrogen bonds gives snowflakes their anisotropic nature. The physical properties of snowflakes vary depending on the direction in which they are measured. For example, the thermal conductivity of snowflakes is different along the six different axes of the hexagonal structure.

Another physical property that varies in snowflakes is their optical properties. When light passes through a snowflake, it is refracted in different directions depending on the orientation of the hexagonal structure. This gives snowflakes their unique and beautiful appearance.

Conclusion:

In conclusion, snowflakes possess anisotropic nature within their structure due to the hexagonal arrangement of water molecules. This gives them unique physical properties that vary depending on the direction in which they are measured.
