Energy change and chemical reactions

Chemical reactions can take in energy or release energy, often in the form of heat. This causes a change in temperature. There are two different types of energy change that can take place.

Basic fusion physics

the probability of a reaction to take place) and also the largest Q-value (the released energy of a reaction) of all varieties of fusion reactions. It produces an alpha particle (or Helium-4 nucleus) and a neutron, and releases 17.6 megaelectron volt (MeV ...

Fusion - Frequently asked questions

The reason why opposite processes release energy can be understood by examining the binding energy per nucleon curve. Both fusion and fission reactions shift the size of the reactant nuclei towards higher bounded nuclei. Does Fusion produce radioactive ...
