===About Nuclear Fusion===
: In a '''nuclear fusion reaction''' the products have less [[mass]] than the reactants as some of the [[mass]] is converted into [[energy]] in the process due to the [[Mass-Energy Equivalence]].
: For a '''fusion''' [[Nuclear Reaction|reaction]] to occur the two [[Atomic Nucleus|nuclei]] must have enough [[Kinetic Energy Store|kinetic energy]] to overcome the [[Electrostatic Force|electrostatic force]] of repulsion between the [[Positive Charge|positively charged]] [[Atomic Nucleus|nuclei]].
: To provide enough [[Kinetic Energy Store|kinetic energy]] to the [[Atomic NucleiNucleus|nuclei]] the [[substance]] must be [[heat]]ed to a [[temperature]] of several million [[Degrees Celsius|degrees Celsius]].
: '''Nuclear fusion''' occurs naturally in the centre of a [[Star]] due to the high [[temperature]]s and [[pressure]].
: '''Nuclear fusion''' is possible in [[laboratory|laboratories]] on [[Earth]] but it cannot be sustained for long periods of [[time]] to produce enough [[energy]] to be useful as an [[Energy Resource|energy resource]].
: '''Nuclear fusion''' in [[laboratory|laboratories]] on [[Earth]] must be done at much higher [[temperature]] than in the centre of [[Star]]s because the centre of [[Star]]s is a much higher [[pressure]] so [[Atomic Nucleus|nuclei]] collide more often.
