Problem: Liquid crystalline phases tend to be more viscous than the isotropic, or normal, liquid phase of the same substance.Why?

FREE Expert Solution

We are asked why liquid crystalline phases tend to be more viscous than the isotropic, or normal, liquid phase of the same substance.

Take note that when most liquids freeze, they transition to an ordered crystalline solid (i.e. rigid with fixed shape and volume). Their respective phase diagrams have a defined liquid and solid phases (i.e. there are no regions between the liquid and solid phases). These liquids are said to be isotropic or are equally disordered in all directions.
