Chemical energy is a form of potential energy found within chemical bonds, atoms, and subatomic particles.Chemical energy can be observed and measured only when a chemical reaction occurs.Any matter that is a fuel contains chemical energy.The energy can be released or absorbed. For example, combustionreleases more energy than is needed to initiate the reaction. Photosynthesis absorbs more energy than it releases.Fuels are a familiar form of chemical energy. While combustion is an example of the release of chemical energy, there are several other examples: 1. Coal: The combustion reaction converts chemical energy into light and heat. 2. Wood: Combustion converts chemical energy into light and heat. 3. Petroleum: Petroleum may be burned to release light and ...
For the most part, chemical energy is energy stored within chemical bonds. In a chemical reaction, chemical bonds are broken and new ones are formed, changing products into reactants. When breaking bonds releases more chemical energy than forming new bonds absorbs, then the reaction is exothermic and heat is released. But, sometimes it takes more e...

Define energy, distinguish types of energy, and describe the nature of energy changes that accompany chemical and physical changes. Distinguish the related properties of heat, thermal energy, and temperature. Define and distinguish specific heat and heat capacity, and describe the physical implications of both.
To know the relationship between energy, work, and heat. Because energy takes many forms, only some of which can be seen or felt, it is defined by its effect on matter. For example, microwave ovens produce energy to cook food, but we cannot see that energy. In contrast, we can see the energy produced by a light bulb when we switch on a lamp.
