( NUCLEAR FUSION )

Which of the following is true about nuclear fusion ?

• It is easy to implement

• It produce less energy than nuclear fission

• It produce more energy than nuclear fission

• It has the ability to occur easily in everyday life

Minimum condition for productive fusion are

• ion density

• confinement time

• high energy

• high temperature

Nuclear fusion is the

• hydrogen nuclei

• joining of two light nuclei

• converted into the energy

• radiation

How many hydrogen are needed for the Proton-proton chain cycle

• 4

• 2

• 8

• 6

which type of magnetic confinement device utilizes twisted magnetic fields to confine plasma

• Stellarator

• Tokamak

In a hydrogen bomb, the fusion process is triggered by a nuclear fission reaction. what is the difference between nuclear fusion and nuclear fission ?

• In fusion one atom is split apart and in fission two atoms are combined together

• Fission and fusion are the exact same process. Fission is just similar scale version of fusion

• Fission can occur naturally , but fusion has only ever been produced artificially

• In fusion two atoms are combined together and in fission one atom is split apart
