Liquid crystals have the useful property that
A) they can behave like liquid semiconductors and make computers more flexible.
B) they can change from a liquid state to a solid state instantly.
C) their transparency can be changed by applying an electric field.
D) they are very strong in one direction but very weak in another.

Question

Quizplus · Accepted Answer

Liquid crystals can change their transparency when subjected to an electric field due to their anisotropic nature (different physical properties in different directions). This property makes them useful in a variety of applications, including displays such as LCDs. However, they do not behave like liquid semiconductors (A), they do not change from a liquid to a solid state instantly (B), and their strength properties are not mentioned (D).
