Can anybody tell me that does the Law of Conservation of Energy hold true during nulcler fission??????

Question

'cause suppose even if I consider the initial thermal(etc.) energy of the fissionable mass =e1 and kinetic energy of the striking nuclear projectile(poton etc.) to be =e2...


then i don think that E3=energy produced by nuclear fission(heat+electromagnetic) is in any way near the sum of e2 & e1??!!!
i.e E3>>>e1+e2

so here the law of consv. of mass-energy holds,but does it mean that we can practically increase the total energy of the universe by a finite value?????

reply fast n plz give req. exp. facts.......

Yes tell me the main thing that is law of conservation OF ENERGY applicable during nuclear fission? if yes then HOW?
BECAUSE TOTAL ENERGY PRODUCED IS FAR MORE THAN INITIAL ENERGY OF REACTANTS???????????1

Answer 1

What is everyone going on about? The major part of the energy produced in a nuclear fission reaction is due to the direct conversion of mass into energy according to E=mc².

All the kinetic energy and whatever other initial energies involved in the process are negligible compared to the awesome output of the conversion of mass into energy.

The law that holds true is the Law of Conservation of Mass and Energy. (Not just conservation of mass, and not just conservation of energy, but conservation of mass AND energy. This is what E=mc² implies.)

Answer 2

Yes the Law of Conservation of Energy holds true in Nuclear Fission.

No Fission does not increase the total Mass+Energy of the universe.

The potential energy in a fissile atom converts into kinetic or thermal energy when the atom splits into smaller more stable atoms. The radient energy of the reactants due to their temperatures and kinetic energy due to their motion is also conserved. The neutrons used to start the process don't just stop moving.

Answer 3

Energy is not a Quantity it is only a power process that indicates what was used to push a mass into motion.
Hence when a mass is is a certain amount of motion it is said that the mass has Energy.
The Law of energy conservation means that you cannot obtain more energy of motion than what you invested in.
In the case of fusion the Energy needed to bind the new Atom cannot be greater than was used to fuse the new Atom. So the excess energy is radiated out of the fusion reaction.
What is really radiated is the excess mass that was not necessary to form the new atom.
Never the less mass is conserved. That means that the total original mass that formed the parent component of the new mass structure is still equal to the new mass structure plus the rejected excess mass. The rejected mass is called mass defect. The velocity of the radiated mass equals the velocity of light.
Therfore if mass is conserved in structuring an atom so is also Energy.
Therefore the Universe as a closed system is conservative;Where the mass and energy content is a constant.On that basis the conservation of mass and energy applies to all atomic structures in the Universe.

Answer 4

The conservation of energy is valid for all systems in our known universe...no exceptions. Nuclear fission produces all kinds of energy, including:

Sonic...sound (especially in bombs)
Light...photons
Radiation...beta, apha, gamma (also photons)
Kinetic...bits and pieces flying around (if its a bomb), and subatomic particles in motion (as they split and become projectiles for further splitting)
Heat...also photons

All these, and maybe some more I've forgotten, have to be included in the energy equation.

The total energy the universe has is constant. But the form of energy is continually changing from one form to another. And, to a point, one form of energy is called mass because it has inertia. That's the mass in E = mc^2.

In the ultimate, all the energy in the universe will become entropy, useless energy. This results, because, in the net, all usefull energy (enthalpy) is used up and that converts it to entropy. This is why cosmologists claim the universe is positive entropic.

Answer 5

You forgot the most important part, that nuclear fission produces a loss of MASS that creates energy = (MASS)*c^2. The sum of these is energy. Given the size of the universe, this is like a drop of water in the ocean.

Answer 6

no way dude, mass AND energy are conservative.

if what you said is true, the nearly 5000 decay/second of 14C in your body would transform you in a ball of plasma. LOL

Answer 7

Not a chance.The power would be to demanding for our planet even if we could tap the suns energy.

Answer 8

again too much
