FUSION NOTES

Requirements for Nuclear Fusion:

Extreme heat and density

What percentage does the conditions occur in the sun’s core

24%

What’s the 1st fusion

Two Hydrogen Nucleous adding up and = Hydrogen isotope or deuterium + positron + Neutrino

How many times does the first Collision and second collision happen

Twice

THE fusion

Hydrogen isotope + Nydrogen Nucleous = Helium isotope, or unstable helium + Gamma Ray

FINAL collision

Helium Isotope + Helium Isotope = 1 helium + hydrogen (two atoms)

Final product:

Helium Nucleus x1 + Hydrogen Nuclei x2 + Positron x2 + neutrino x2 Gamma ray x2

What are the final products

Positron, Neutrino, Gamma ray

Info of Positron

• anti-electron

• + charge

• Carries away +charge from a proton, converting it into neutron

Info of Neutrino

• extremely small mass

•weak force (E)

•carries away some E during fusion

Info of Gamma Ray

-photon

-high energy light wave

-carries away lots of E during fusion

(IMPORTANT) what’s the law of conservation of mass

Matter can never be created nor destroyed, only change forms

(IMPORTANT) What’s the law of conservation of energy

Energy can never be created nor destroyed, only change forms

Einstein’s equation:

E=m.c 2^ (Energy and mass go towards eachother)

The 2.013×10 ^ 26kg of mass we “lost” during fusion was…

Converted into energy

Does Fusion follow laws of conservation?

Yes, we know baes of Einstien’s equation

Does mass convert into energy during stellar fusion?

Yes
