Physics
Nuclear fission and fusion
Nuclear fissions
Nucleus splitting into half
unstable nucleus
hits the
slow moving neutron
the unstable nucleus
splits into 2
creating
2 daughter nuclei
while the nucleus splits,
kinetic energy
and
gamma radiation
is released
and 3
high speed
moving neutron is released
Chain reaction
the fast moving neutron that is released slows down until it is suitable to do another nuclear fission which is a chain reaction
nuclear power station
the
fission reaction
generates heat energy
in the
reactor
the
heat energy heats up the water
the heated water goes to the
steam generator
where
steam is produced
the steam produced
spins the turbine
that is connected to the
generator
then
electrical current
is produced there
Nuclear fusion
Definition
2 nuclei joining together
Energy source
of
sun and star
2 isotypes/ atom
of
hydrogen
hits
each other
moving in high speed
The 2 nuclei
forms a large nuclei
Large amount of
kinetic energy
is produced
the mass of the large nuclei is
smaller
than the
2 isotypes/atoms
Radioactivity and particles
Radioactivity
Alpha
2 neutron and 2 proton(same as helium nucleus)
Positive charge
Very ionizing ( big and heavy)
Beta
Gamma
