Fission and fusion is an example of what kind of energy?

One type of atom (element or isotope) is converted to another. This is called nuclear reaction.


In a nuclear reaction WHAT does not have to be conserved?

While overall ENERGY has to be conserved, MASS does not. In a nuclear reaction mass can be converted into energy so the mass of the products may be less than the mass of the reactants. The difference in mass is converted into energy as Einstein's equation describes (E=MC squared). In a chemical reaction MASS has to be conserved.


How does the law of conservation of energy apply to nuclear energy?

Before the reaction, the energy exists as potential energy, caused by the nuclear forces. After the reaction, the energy goes away as gamma rays for example, which may eventually be absorbed and get converted to heat.


What did einstein suggest and later proved happened to some of the mass in a nuclear reaction?

It was converted to energy.


What change takes place in a nuclear fusion reaction?

1 mater is converted ti energy


Is energy conserved in a nuclear reaction?

Yes. Basically, energy is ALWAYS conserved. The popular saying, that in a nuclear reaction mass is converted to energy, is plainly wrong, since both mass and energy are conserved. Read about "mass deficit", for example in the Wikipedia, for more details.


What is a sentence for energy?

Nuclear energy is obtained by the fissioning of nuclei of uranium235, in a controlled chain reaction in a nuclear reactor, which produces heat that can be converted to electricity by normal power plant methods.


How you change nuclear energy to mechanical energy?

The way this is handled is that the energy from the nuclear reaction is converted into heat. The remainder is handled like any heat engine; several possibilities exist for this. For example, water might be converted into vapor, and the pressure of the vapor moves turbines.


What energy is released in a nuclear reaction?

Nuclear Energy


Is nuclear energy a fission or fusion reaction?

Nuclear energy is either:fission reaction, orfusion reaction, orradioactive decay


What happens to the mass lost in nuclear fusion?

its converted to energy


Can nuclear energy work with other forms of energy?

Nuclear energy is converted to electrical energy in a nuclear power plant.
