Fusion & Fission Spring 24

Front

What is Fission?

Back

Fission is the process of splitting a heavy nucleus into smaller nuclei, accompanied by the release of energy.

Front

What is Fusion?

Back

Fusion is the process where two light atomic nuclei combine to form a heavier nucleus, releasing energy in the process.

Front

What is a Chain Reaction in the context of Fusion?

Back

A chain reaction in fusion refers to a series of reactions where the products of one reaction initiate further reactions, often involving many steps or mini-reactions.

Front

Where does Fusion occur naturally?

Back

Fusion occurs naturally in stars, including our sun.

Front

What is the primary energy source for stars?

Back

The primary energy source for stars is nuclear fusion.

Front

What is the difference between Fission and Fusion?

Back

Fission involves splitting heavy nuclei, while fusion involves combining light nuclei.

Front

What is a common example of a Fission reaction?

Back

A common example of a fission reaction is the splitting of Uranium-235 in a nuclear reactor.

Front

What is the role of temperature in Fusion?

Back

High temperatures are required for fusion to occur, as they provide the energy needed to overcome the repulsive forces between nuclei.

Front

What is Half-Life?

Back

Half-life is the time required for half of the radioactive nuclei in a sample to decay.

Front

What type of reaction is radioactive decay?

Back

Radioactive decay is a type of fission reaction where unstable nuclei lose energy by emitting radiation.
