INTRODUCTION
The fundamental system which makes up the world around us is known as matter . From the air we breathe to the stars in the universe, each and every thing is composed of matter. To understand the world where we live it is essential to know about the properties and behavior of matter. One of the key concepts in physics and chemistry is the study of states of matter,which is referred to as the different forms which matter can take depending upon the temperature,pressure and other conditions. In this blog post, we will explore the four main states of matter that are solid,liquid,gas ,along with their unique characteristics and properties.
SOLIDS
The substances which have fixed shape and volume are known as solids. They are considered as one of the states of matter along with liquid,gas . They are best known for their rigid structure and resistance to change in shape and volume.
>Properties of Solids
They have various properties which distinguish them from the other states of matter. The properties are as follows:
●Rigidity: They are rigid and maintain their shape even when external force is applied.
●Fixed Shape: They have a fixed shape which is determined by the arrangement of their particles.
●Fixed Volume: They have a fixed volume which is determined by the amount of space occupied by their particles.
●High density: They typically have high density when compared with liquids or gases.
>Types of Solids
There are various types of Solids which includes:
●Crystalline Solids: They have a regular arrangement of particles in a repeating pattern. For example diamonds and quartz.
●Amorphous Solids: They have a random arrangement of particles. For example glass and rubber.
●Polycrystalline Solids: They are made up of many small crystalline regions. For example metals and alloys.
>Characteristics of Solids
They have various characteristics which are determined by their structure and composition, their characteristics are as follows:
●Melting Point: The temperature at which solid changes its state into liquid is known as a melting point of solid.
●Hardness: The amount of resistance which a solid can show to scratching and abrasion is known as hardness of a solid.
●Conductivity : Most of the Solids are good conductors of electricity and heat while few are insulators too.
>Examples of Solids
Some of the examples of solids are as follows:
●Metals: They are the Solids which are typically shiny,malleable and good conductors of heat and electricity. For example copper and iron.
●Minerals: They are the naturally occurring Solids which have a specific composition and structure. For example quartz and diamonds.
●Polymers: They are the solids which are made up of long chains of molecules. For example plastics and fibres.
LIQUIDS
The substances which have a fixed volume but can change their shape are known as liquids. They are considered as one of the states of matter along with Solids,gases . They are known for their ability to flow and taking the shape of their container.
>Properties of Liquids
They have various properties which distinguish them from other states of matter. The properties are as follows:
●Fluidity: They can flow and change their shape in response to the external forces.
●Fixed Volume: They have a fixed volume which is determined by the amount of substance present.
●Variable shape: They can take the shape of their container.
●Surface Tension: They have a surface tension which causes them to behave in certain ways like the formation of droplets.
>Types of Liquids
There are various types of liquids,some of them are as follows:
●Polar Liquids: They have molecules which have a slight electric charge that allows them to form hydrogen bonds. For example water and ammonia.
●Nonpolar Liquids: They have molecules which do not have a slight electric charge. For example oil and gasoline.
>Characteristics of Liquids
Liquids have various characteristics which are determined by their composition abd structure,their characteristics are as follows:
●Viscosity: It is considered as it's resistance to the flow.
●Boiling Point : The temperature at which liquid changes its state to become a gas is known as Boiling point of a liquid.
●Surface Tension : The energy which causes it to behave in certain ways such as forming droplets is known as Surface tension of a liquid.
>Examples of Liquids
Some of the examples of liquid are as follows:
●Water: It is a polar liquid which is essential for life.
●Oil: It is a nonpolar liquid which is used in variety of applications like lubrication and production of energy.
●Blood: It is a complex liquid which carries Oxygen and nutrients to the cells throughout the body.
GASES
The substances which have neither a fixed shape nor a volume are known as gases. They are considered as one of the states of matter along with Solids,liquids. They are best known for their ability to expand and fill their container.
>Properties of Gases
They have various properties which distinguish them from other states of matter,their properties are as follows:
●Expandibility: They have the ability to expand and fill their container.
●Compressibility : They can be compressed to fill in the containers.
●Low Density : They typically have low densities when compared with Solids and Liquids.
●Diffusion : They can diffuse and mix with other gases.
>Types of Gases
There are various types of gases which are as follows:
●Noble Gases: These are the group of elements which are unreactive and stable. For example helium,neon and argon.
●Diatomic Gases: These gases are the molecules which are composed of two atoms of the same element. For example Oxygen (O2),Nitrogen (N2) and hydrogen (H2).
●Greenhouse gases: These are the gases which trap heat in the atmosphere and contribute to global warming. For example carbon dioxide, methane and water vapor.
>Characteristics of Gases
They have various characteristics which are determined by their composition and structure. The characterstics are as follows:
●Pressure: The force exerted by the gas on per unit area on the walls of the container is known as pressure of the gas.
●Temperature: The measure of average kinetic energy of its particles is known as temperature of the gas.
●Volume: The amount of space occupied by the particles of the gas is known as the volume of the gas.
>Examples of Gases
Some of the examples of gases are as follows :
●Air: It is a mixture of gases which surrounds the earth which includes nitrogen and oxygen with trace amounts of other gases.
●Helium: It is a noble gas which is lighter than air and is mostly used in balloons and airships.
●Natural Gas: It is a fossil fuel which is primarily composed of methane ,which is used for heating,cooking and generation of electricity.
