liquid crystalline state

The liquid state lies between the gaseous and the solid state. Liquids are neither completely disordered nor completely ordered. The cohesive forces between the liquid particles are strong enough to keep them together but these particles do no..

A solid has a definite characteristic shape tends to resist deformation of its shape is relatively non compressible For example, diamond Solids can be classified as: Crystalline Amorphous In a crystalline substance the solid is characterised by a very definite, ..

In liquid water, water molecules are held together by intermolecular hydrogen bonds. Each oxygen atom can form two hydrogen bonds utilizing both the lone pairs on it. Experimental studies suggest that liquid water consists of aggregates of varying number of water molecules held..

Liquids do not have a definite shape. They take the shape of the container. Thus, we can specify a liquid by its volume. Hence, we can speak of volume expansion only for liquids. Expansion of liquids is much greater than that of solids. A liquid i..

When a solid is heated it starts melting at a certain fixed temperature (melting point). At this stage even when the heating is continued, the temperature does not change until the whole of solid is converted into liquid. The state when solid and liquid phases of..

Vapour pressure is defined as the partial pressure exerted by the vapors above the liquid surface in equilibrium with liquid at a given temperature. fig 3.3 In illustrations 1a and 1b, the liquid and vapor states of a given substance are represented. The indi..

Transmission of pressure in liquid Pascal's Law Pascal's law states that pressure applied to an enclosed liquid, is transmitted equally to every part of the liquid. This can de demonstrated using a glass vessel as shown in figure above. When forc..

The first three aliphatic acids are colorless liquids with pungent smell. The next six are oily liquids with an odor of rancid butter. The higher members are colorless, odorless, waxy solids. Benzoic acid is a crystalline soli..
