Breaking a molecule release energy.
The coubustion of gasoline is an example of energy released by chemical changes
Changes in energy themselves are not considered chemical changes. Instead, changes in energy may occur as a result of a chemical change taking place, such as in an exothermic or endothermic reaction where energy is either released or absorbed.
Yes it is released/ absorbed during chemical changes.
Chemical that changes to heat that changes to mechanical.
When energy is absorbed or released, it can be associated with both chemical and physical changes. Chemical changes typically involve the breaking or forming of bonds between atoms, resulting in energy changes, while physical changes involve altering the state or arrangement of molecules without affecting their chemical composition, which can also result in energy absorption or release.
Chemical changes can either absorb or release energy. When a chemical reaction releases energy, it is called an exothermic reaction. This means that the products of the reaction have lower energy than the reactants, and the excess energy is released in the form of heat or light.
The mitochondria changes food energy to chemical energy.
Oxygen is not changed into energy. However, energy may be released when it combines with a range of other chemical compounds and elements.
The mitochondria changes food energy to chemical energy.
The mitochondria changes food energy to chemical energy.
Energy is required to break chemical bonds in reactant molecules in order to initiate a chemical reaction. This initial input of energy is called activation energy. In addition, energy is released or absorbed during a chemical reaction, which can result in changes in temperature.
The body changes chemical energy to mechanical energy to power muscle contractions and movement.
