"We really love eTutorWorld!"
"We really love etutorworld!. Anand S and Pooja are excellent math teachers and are quick to respond with requests to tutor on any math topic!" - Kieran Y (via TrustSpot.io)
"My daughter gets distracted easily"
"My daughter gets distracted very easily and Ms. Medini and other teachers were patient with her and redirected her back to the courses.
With the help of Etutorworld, my daughter has been now selected in the Gifted and Talented Program for the school district"

What is Chemical Energy?
Chemical energy can be found in a variety of sources, including fuels such as gasoline, natural gas, and coal, as well as in food and batteries. When these compounds are burned, digested, or otherwise reacted, the chemical energy is converted into other forms of energy, such as heat, light, or electrical energy.
The amount of chemical energy stored in a substance depends on the type and arrangement of atoms in its molecules, as well as the strength of the bonds between those atoms. Some chemical reactions release more energy than others, depending on the types of molecules involved and the conditions under which the reaction takes place.
Chemical energy is a power that is kept in chemical bonds, such as those between atoms and molecules.
A chemical reaction is a process by which atoms are rearranged as a result of a chemical change, leading to the production of a new substance.
When heat is created as a byproduct of a chemical reaction, it is called an exothermic reaction.
Characteristics of Chemical Energy
There is a workable potential in chemical energy. It was kept in the atom-to-atom bonds. The energy is released when those bonds are broken. This can be used to carry out tasks like moving or heating something.
Other types of energy, such as electrical or thermal energy, can be created from chemical energy. In order to produce new substances, it can also be used to form new bonds between atoms.
“There have been times when we booked them last minute, but the teachers have been extremely well-prepared and the help desk at etutorworld is very prompt.
Our kid is doing much better with a higher score.”

Examples of Chemical Energy
Plants require solar energy to convert carbon dioxide into sugar and then water. Chemical bonds that hold the chemicals together keep sugar, water, and carbon dioxide together.
For instance, oxygen, carbon, and hydrogen atoms are the building blocks of all sugars and are held together by chemical bonds. These atoms don’t automatically bond together; rather, energy is needed to keep them together.
The hydrogen, carbon, and oxygen atoms are combined to form sugar in plants using solar energy. This is an appropriate example of energy conversion where energy is transferred from one form to the other. Here, solar energy is converted into chemical energy to keep the system from disintegrating.
Chemical energy can be seen in the burning of wood. Wood is composed of complex molecules such as cellulose and lignin, which contain a significant amount of stored chemical energy. When wood is burned, the heat from the fire breaks down the chemical bonds in these molecules, releasing the stored energy in the form of heat and light.
Chemical energy is also present in the food we eat. The molecules in food contain stored energy that is released when they are broken down during digestion. This energy is then used by our bodies to carry out various functions such as movement and growth.
Batteries are another common example of chemical energy. A battery is composed of two electrodes, each made of a different metal or material, immersed in an electrolyte solution. Chemical reactions between the electrodes and the electrolyte produce a flow of electrons, creating an electrical current that can be used to power devices such as flashlights or cellphones. The chemical energy stored in the battery is converted into electrical energy.

Chemical Energy FAQS
What does the term "chemical energy" mean?
Bonds in chemical compounds hold energy. Chemical energy can be released during a chemical reaction, frequently in the form of heat; these reactions are referred to as exothermic energy. The chemical energy in a battery can also be used to create electrical fuel via electrolysis.
What is chemical energy?
Chemical energy is all the atomic and molecular energy that is held within the bonds of chemical compounds. These energies are released during chemical reactions. Once chemical energy has been released from a substance, it is frequently transformed into an entirely new substance.
What kind of sound energy is that?
Sound energy is created when something vibrates. Both directions of sound propagate as waves. Air, water, wood, and even metal are all forms of sound that need a medium to travel through. Voices, whistles, musical instruments, and horns are a few examples.
What does the body's chemical energy entail?
Chemical energy is the form of potential energy that is contained in chemical bonds. Some of the chemical energy in the bar is transformed into the fuel molecules the body needs, but some of it is released, for example as heat.
