What are liquid crystal intermediates?
They are some special chemicals for the production of liquid crystals. These chemicals are the research focus of liquid crystal polymers. Those synthetic polymers which has been commercialized include aromatic polyamide (Kevlar and etc.), thermotropic liquid crystalline copolyesters(Xydar, Vectra A and etc.) and thermotropic liquid-crystalline polyester-amides(Vectra B). Generally most of them have linear molecules. Their value is relatively high. See the related link for information about 2-Bromo-4-fluorotoluene that are used as an intermediate of liquid crystal materials.
What is a mood ring made out of?
A mood ring is typically made out of a hollow glass or quartz shell filled with thermotropic liquid crystals that change color based on the wearer's body temperature. The liquid crystals are sensitive to temperature changes and shift colors to reflect the mood or emotions of the person wearing the ring.
What is the difference between solid crystals and liquid crystals?
Solid crystals have a fixed, ordered arrangement of molecules or atoms, while liquid crystals have a partially ordered structure that can flow like a liquid but still exhibit some properties of a solid. Solid crystals have a defined melting point where they transition to a liquid state, while liquid crystals have a range of temperatures over which they exhibit liquid-like and solid-like properties.
Will a thermotropic organism grow in the direction of the heat?
no a thermotropic organism grows away from the direction of heat.
Can crystals be formed from minerals dissolved in liquid when the liquid evaporates?
On evaporation the crystals so formed are in the form of solid(in criss cross manner) and on crushing those crystals they become change into powder.

How can I make crystals using salt and vinegar?
To make crystals using salt and vinegar, first dissolve salt in vinegar to create a saturated solution. Then, allow the solution to evaporate slowly in a container. As the liquid evaporates, salt crystals will form. You can also try adding food coloring to create colored crystals.
What unusual property do liquid crystals have when they melt?
Liquid crystals start to flow during the melting phase similar to a liquid, but they do not lose their ordered arrangement completely, as most substances do. Liquid crystals will retain their geometric order in specific directions.
Will a thermotropic organism grow in the direction of the heat?
no a thermotropic organism grows away from the direction of heat.
