What are liquid crystals ?
Using 3D animated diagrams, this video defines liquid crystals and gives some examples of their use. How many distinct forms do liquid crystals take, Liquid crystals' properties and practical uses, Where can you find liquid crystals, For the Eleventh Grade Chemistry Exam in Urdu or Hindi, please explain what kind of liquid crystals are used in LCD screens.

"The phase between solid and liquid, with qualities between those of real crystalline solid and true liquid (clear liquid), is called liquid crystal."
Flowing like a liquid but with some degree of order in the arrangement of its molecules, liquid crystals (LCs) are an unusual phase of matter.

Types of Liquid Crystal:
Thermotropic Phase
Nematic Phase
Smectic Phase
Cholesteric Phase

Liquid Crystals Uses:
1.As temperature sensors in thermometers.
2. To find the point of potential failure in electrical circuits.
3. To locate blockage in vein, arteries, infections and tumours by skin thermograph.
4.In the display of electrical devices(LCD) like digital watches, calculators & computers etc.
5.As a solvent in chromatography.
Discovery of first liquid crystal:
