molecules in liquid state

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 ..

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 not occu..

A liquid possesses a definite volume but not definite shape. The substances in liquids have particles, which are loosely packed and bound to each other by forces weaker than those of solids. This makes a liquid mobile and shapeless resulting in its taking up the shape..

Vapour Pressure of Liquids - 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 gi..

Solid-Liquid Equilibrium - 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..

When a liquid is placed in an open container it disappears completely after some time. However, when the same liquid is placed in a closed container, even after a long period only a part of the liquid disappears. The obvious difference is that the vapours of the l..

The vapour pressure of a liquid depends upon the nature of the liquid. When intermolecular forces are weak, the molecules tend to escape readily and therefore, the equilibrium vapour pressure is high. Vapour pressure of liquids provides an indication of the ..

Expansion of Liquids - 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 ..

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, well-defined externa..
