THE NATURE OF LIQUID

Chemistry is the study of story formation and modification. The matter is made up of very small particles and these particles are so small that we cannot see them with our physical eyes. Chemistry is responsible for the study of the behaviour of matter .Chemistry is about – the formation, composition, and characteristics of an object and the phenomenon that occurs when different types of matter change.

There are basically the three states of matter: 

1. Solids
2. Liquid
3. Gases

Liquid:

The particles in the liquid are able to flow freely, so although the liquid has a precise volume, it does not have a precise shape. The liquid is a phase in which molecules can move freely, but meet the forces that keep them together. The liquid takes the form of a container in which it is stored. The fluid distribution rate is higher than that of solids. The gravitational force between the particles is weaker than firm.

Most liquids are resistant to pressure, although some may be suppressed. Unlike gas, the liquid does not dissolve to fill the entire surface of the vessel, and it retains a constant density. A distinctive feature of the liquid state is the local concentration, which leads to the actions of watering. Water is not the most common liquid in the world.

For example, if you pour a glass of water onto the floor, the water will often condense rather than spread into a thin, thin layer. As a result, we separate water as a liquid under normal conditions.

Features of Liquid:  

• The liquid is similar to the fluid. 
• In contrast to solids, liquid motes have very little freedom of movement. The force binds the molecules to a temporary solidity in the liquid, allowing the liquid to flow while it is solid. 
• However, it can squeeze into any shape, If the liquid is put in a bag.
•  Unlike gas, a liquid is almost compressed, which means it takes about a constant volume over a wide range of pressures; it usually does not expand to fill the space available on the ship but forms its surface, and may not always be in contact with any other liquid. 
• These spaces make the liquid suitable for operations such as hydraulics. 
• The liquid episodes are bound tightly but not tightly. They are able to move around freely, acting with a limited range of flyspeck movement.
• As the temperature rises, the rising climate of the molecules causes the distance between the molecules to increase. 
• When the liquid reaches its boiling point, the binding force binds to the nearly compact motes and breaks, and the liquid shifts to its gas state except when it is very hot.
•  However, the distances between the molecules decrease, if the temperature drops. When the liquid reaches its freezing point the molecules will usually lock in a straight line, called the formation, and the bonds between them become very strong, converting the liquid to its solid-state except when it is very cold.

Properties of liquid: 

• The change in the density is very less and is affected by the pressure. It remains fairly constant throughout.

• The mechanism of wetting by liquid is due to the surface tension.

• There is greater freedom of particles to move than the solids.

• Liquids can either be miscible or non-miscible. 

For instance, water and ethanol are miscible liquids, whereas oil and water are immiscible liquids. 

•  The existence of liquid is dependable on the narrow temperature and pressure range. 

•  Almost incompressible fluid in nature. 

Characteristics of Liquid:

There are numerous characteristics of the liquid. These are as follows: 

1) The liquid has a constant volume but no fixed shape.

2) The liquid can be compressed. Greater pressure is needed to press on them.

3) The liquid has a lower consistency than the solidity.

4) The intermolecular magnetic field is weaker than that of solids.

5) They have a large space between the tracts. 

Applications of Liquid: 

• Liquids have a variety of uses, such as lubricants, solvents, and coolers.
• Most liquids are used as solvents, to dissolve other liquids or solids.
• Heat can be removed by moving the liquid through a temperature changer, such as a radiator, or the heat can be removed by the liquid during evaporation.
• Liquid films are used to cool rockets.
• Liquids are often used in cooking for their better heat transfer properties.
• In tribology, liquids are studied for their properties as fats.

Conclusion:

The liquid state of the substance is the intermediate phase between solids and gas. Like solid particles, the particles in a liquid are subject to intermolecular attraction; however, liquid particles have more space between them, so they do not concentrate in space. The interaction between the particles in the liquid keeps the volume of the fluid constant.
