Introduction to thermal energy and states of matter:
Matter available in three states – solids, liquids and gases. Gases differ from the others in that gases are not rigid and are highly compressible. Chemistry deals with the structure of matter and the changes which it takes, it is appropriate to know about “ Matter”.
Matter may be defined as ‘Anything which occupies space and has mass.’ Some examples of matter are water, air, plants etc. States of Matter is classified in two different ways.
Classification of states of matter
Physical classification of states of matter:
On the account of rigidity, volume and shape, matter is classified into solid, Liquid or gas. These are the states of matter,
Solids are rigid substances which have definite shape and definite volume.
Example: A piece of metal, a wooden box etc.
Liquids have definite volume but not has definite shape. They can take the shape of the containers in which they are placed.
Example: milk, fruit juice etc.
Gases have no definite shape and definite volume.
Example: nitrogen, air etc.
Plasma is the fourth state of matter, it contains gaseous ions and it available at very high temperature.

Chemical Classification of states of matter:
On the account of chemical composition, matter can be classified as element, compound or mixture. These are the states of matter,
a) Elements:
These are the substances which cannot be further decomposed by ordinary chemical means. These are about 116 elements known so far, out of which nearly ninety(90) are naturally occurring elements, while the rest are prepared artificially by the nuclear process.
b) Compounds: These are the substances which can be decomposed into two or more simple substances by ordinary chemical method. A compound is formed by the combination of two or more elements. A compound must has a definite chemical composition. Examples: Water, Ethane, methane etc.
c) Mixtures: These are the substances which may be separated into their components by some physical methods. In a mixture, the elements retain their properties. Example; air, solution of water and salt etc.
Thermal energy
Due to the random movements of atoms and molecules, internal energy develops in a system, this part of the internal energy refers to Thermal energy. The excellent source of thermal energy available to all living organisms is the sun, the sun’s thermal energy is increased by the nuclear fusion in the sun. In the form of radiation thermal energy emitted by the sun, it is called Heat. Thermal energy is the form of kinetic energy, which is produced by the random movements of molecules in matter. Thermal energy may be increased or decreased.

Thermal Energy Com
Introduction:
Thermal energy storage may be refer to the number of technologies that Store energy in a thermal reservoir for later reuse. They can be employed to the balance energy of demand between the day time and night time. The thermal reservoir to be maintained at the temperature of above (hotter) or below (colder) than that of the ambient environment. The principal of the application today is the production of ice chilled water, or eutectic solution at night, which is then used to cool environments during the day.
I like to share this Activation Energy Equation with you all through my article.
Economics
The most widely to used form of this technology is in large building or campus-wide air condition or chilled water systems. Air conditioning systems,is especially in the commercial buildings, are the most significant contributors to the peak electrical loads seen on hot summer days. In this application is the relatively standard chiller is run at night to produce a pile of ice. Water is the circulated through the pile during the day to produce chilled water that would normally be the daytime output of the chillers.
A partial storage to the system minimizes capital investment by running the chillers 24 hours a day. At night of the produce ice for storage, and during the day they chill water for the air conditioning system, their production augmented by water circulating through the melting ice. Such a system is usually runs in ice-making mode for 16 to 18 hours a day.
Having problem with First Law of Thermodynamics Definition keep reading my upcoming posts, i will try to help you.

Facts About Thermal Energy
Interesting facts about Thermal Energy:
Thermal energy is brought forth and appraised by heat energy of whatever form. It is induced by the expanded process or speed of atoms in a content, which successively drives temperature to climb up consequently. Earth contains many natural sources of thermal energy on it which results in the availability of best optional energy to humans. I like to share this All Types of Energy with you all through my article.
The laws of thermodynamics explicate that energy in the form of heat can be commuted from one object to another. For example, putting fire under a vessel of wax will cause the wax to melt up as a result of the expanded atom drift. Here the process that thermal energy of the fire is transmitted to the wax upto some extent.
The laws of thermodynamics has granted mankind to tackle natural sources of heat to produce thermal energy. The sun, ocean, and geothermic sources such as volcanoes, can all be called as the most beneficial generators of thermal energy. Solar thermal power is one among the best form of thermal energy available today.
Disadvantage
But the biggest disadvantage of this method is that we need to have sun visible for more time to collect the power. However the technology has improved so much that many devices has come up for the sake of absorbing and storign the solar energy and to use it whenever we require.
Is this topic Gravitational Potential Energy Equation hard for you? Watch out for my coming posts.
Utilization of Solar Energy
Some of the contemporary devices used by solar energy
Watches, cooking tools, radios, lanterns, GPS systems, heaters, traffic signals.
These are some of the devices used in modern day to absorb the energy from sun and to utilize it as an alternate energy. Thermal energy is an wonderful source of energy. If we people learn that how to utilize the natural resources effectively by storing, maintaining and to commute it properly, we can majorly reduce our dependancy on artificial forms of energy.
