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.

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.

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.
Liquid crystals appear similar to liquids, but they have properties of both liquids and solid crystals. Under polarized light, they exhibit colorful patterns due to their anisotropic nature, meaning their molecules have different properties depending on their orientation. Liquid crystals can be transparent or opaque, depending on their structure and arrangement of molecules.

Liquid crystals are certain long chain organic chemicals that, although liquid they have a strong tendency to align in "crystal like" arrays. Normal liquids have no (or very little) order, liquid crystals have order approaching that of solid crystals. Liquid crystals are useful in electronics (displays), temperature sensing (indicators), and other technologies because application of various stresses (e.g. electric field, heat) cause them to change their "crystal" properties in ways that solid crystals can't. These changes can then usually be made visible.

When liquid rock cools slowly, crystals will be bigger because there is more time for the crystals to grow and develop before the rock solidifies. In contrast, when liquid rock cools quickly, crystals are smaller because there is less time for them to form and grow.
