Jun 11, 2020 · 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, combustion releases more energy than is needed to ...
chemical energy, Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic. Reactions that require an input of heat to proceed may store some of that energy as chemical energy in newly formed bonds.

The potential energy stored within chemical bonds can be harnessed to perform work for biological processes. Different metabolic processes break down organic molecules to release the energy for an organism to grow and survive. Figure 6.2.1 6.2. 1: Chemical energy: The molecules in gasoline (octane, the chemical formula shown) contain chemical ...
Sep 27, 2021 · Light bulbs transform electrical energy into light and heat energy. Gas stoves transform chemical energy from natural gas into heat energy. Plants perform one of the most biologically useful energy transformations on earth: that of converting the energy of sunlight to chemical energy stored within organic molecules (Figure \(\PageIndex{1}\)).
5.1: Energy in Biological Systems. Living organisms are made up of cells, and cells contain an enormous collection of biochemical components. Living cells, though, are not random collections of these molecules. They are extraordinarily organized or “ordered”. By contrast, in the nonliving world, there is a universal tendency to increasing ...
Aug 5, 2019 · Chemical energy is the energy contained in the internal structure of an atom or molecule. It is a measure of a substance's capacity to transform into another substance via a chemical reaction. This energy could be in the electronic structure of a single atom or in the bonds between atoms in a molecule. Chemical energy is converted into other ...
