Fussion And Fission!?

Question

I need to know the fussion and fission for.

Nuclear Bombs

and Nuclear power for submarines/ships

Thanks!

Answer 1

Fission is the act of splitting the nucleus of an atom, releasing huge amounts of energy.  This can either be done in fractions of a second, releasing huge amounts of energy at once (nuclear bomb) or slowly, with controlled energy release (nuclear reactor).  This is usually done with uranium or plutonium.

Fusion is taking two smaller nuclei, and combining them into one.  This releases even more energy than fission, and makes much more powerful bombs, usually made with isotopes of hydrogen.  It's also the same process that happens in the sun (or any star).  However, we haven't been able to harness this as a stable source of energy.

It gets a lot more complicated than that, but those are the basics.

Answer 2

When atoms are split, they release huge amount of energy.This is fission

When atoms melt and form higher grade of atoms,they have energy  that is mass is converted into energy.That is fussion

First method  we make atom bombs

second method  hydrogen bombs

We get Suns enegy That is fussion

Heat from Fission reactors are used to generate steam by heat exchanger,This steam runs a turbine which in turn run the propeller of the submarine or ship

4 hydrogen atoms are fused to gether and forms a helium atom and small percentage of mass is converted into energy in this process that is fussion  at the core of all stars.

Answer 3

Energy is released when elements lighter than iron are fused into heavier elements. Hydrogen fusion (into helium) is what powers the stars and is the most efficient kind of fusion; fusing heavier elements requires higher temperatures and densities and releases progressively less energy up until iron, which releases none.

Elements heavier than iron only release energy when their atoms are split into lighter elements in the process called fission, and more energy is released from heavier elements.

When these processes are controlled they can be used to generate abundant and cheap energy; when they are uncontrolled and occur rapidly the result is a hydrogen (fusion) or "atomic" (fission) bomb. Present-day nuclear reactors all operate on fission reactions with uranium as fuel and therefore produce dangerous levels of radioactivity, a big disadvantage. So far controlled fusion reactions are too difficult to manage, but research is continuing because the result would be even cheaper and safer energy since the fuel will be the most abundant element anywhere: hydrogen obtained from plain water.
