Question

26. Which of the following shows anisotropy?
A. Naphthalene
B. Polyurathane
C. Cellophane
D. Teflon​

Answer 1

Cellophane is shows the anisotropy.

Explanation:

It is an anisotropic material and also it acts like a calcite crystal.

Ansiotropy is the property of any substances which can shows the physical properties of the different molecular axis. If we consider a cube then we can see the atoms in their corresponding axis. There are many materials are anisotropic.

Wood is one of them, all stems of the plants are the ansiotropy in nature.

Answer 2

Answer:

C. Cellophane is the right answer.  

Explanation:

• Cellophane shows anisotropy.
• Cellophane is a transparent sheet made of regenerated cellulose.
• It has minimum permeability to air, oils, greases, bacteria, and water.
• People can use such materials for food packaging and Cellophane is highly permeable to water vapour.
• Anisotropy is nothing but the property of being dependent in a certain direction and which might also imply different properties and aspects in different directions and sometimes also as opposed to isotropy.
