Basically, any compound contains chemical energy that can be released when its chemical bonds are broken. Any substance that can be used as a fuel contains chemical energy. Examples of matter containing chemical energy include: Coal: Combustion reaction converts chemical energy into light and heat....
Anaerobic respiration is aset of chemical reactionsthat allows cells to gain energy from complex molecules without oxygen. Your muscle cells perform anaerobic respiration whenever you exhaust the oxygen being delivered to them, such as during intense or prolonged exercise. Anaerobic respiration by yeast ...
Fireworks are a great combination of science and innovation. They are made of high-energy compounds, which create explosions. When you provide enough heat (activation energy), they undergo several chemical reactions in rapid sequence. More specifically, the high-energy compounds densely packed inside ...

to the atmosphere. Oxygen formscompoundsby reaction with practically any other element, as well as by reactions that displace elements from their combinations with each other; in many cases, these processes are accompanied by the evolution of heat and light and in such cases are called combustion...
Chemical energy is a form of potential energy because, according to the chemical potential energy definition, it is energy which can be released as heat or work by a chemical reaction. Some of the other possible effects of reactions mentioned in previous examples are simply different manifestations...
Problems of the heat energy efficient usage in the chemical industry have been divided into three principal groups: (1) application of heat pumps, (2) application of multistaged processes, and (3) improving the heat transfer. A detailed description of individual solutions is presented....
