What is a example of nuclear to chemical?
An example of nuclear to chemical conversion is the production of hydrogen gas from water using nuclear reactors like pressurized water reactors or high-temperature gas-cooled reactors. This process, known as nuclear hydrogen production, involves splitting water molecules via high-temperature electrolysis or thermochemical reactions to obtain hydrogen gas as a clean energy source.
What is meant by nuclear reaction at very temperature?
there is no end-scale "highest" temperature, to put this in easy terms : the bigger the bang the higher the temperature, to answer the Question: the highest temperature would probably be the temperature created when the big-bang occurred.
Why does a high temperature favor a nucleophilic elimination over nucleophilic substitution?
A high temperature increases the energy of the system, allowing for more kinetic energy that promotes elimination reactions over substitution reactions. In elimination reactions, the leaving group is expelled with the nucleophile attacking the electrophilic center simultaneously. In contrast, in substitution reactions, the nucleophile replaces the leaving group directly.
Why graphite bars are used in nuclear reactions?
Graphite bars are used in nuclear reactions because they act as a moderator, slowing down the neutrons produced in the reaction. This helps increase the likelihood of neutron interactions with uranium atoms, facilitating the nuclear chain reaction. Additionally, graphite's ability to withstand high temperatures and its chemical stability make it a suitable material for use in nuclear reactors.
Newly formed atoms more neutrons and kinetic energy are all?
Newly formed atoms can have varying numbers of neutrons depending on the element produced. They also have high kinetic energy as they are formed during nuclear reactions, which release a significant amount of energy.

What is the critical temperature at which nuclear reactions begin?
For nuclear fission reactors there is no critical temperature, though they do have a temperature coefficient which makes the efficiency of the chain reaction vary slightly with temperature. This can be negative or positive, obvously a negative coefficient is preferred and is safer. Nuclear fusion is another matter, and very high temperatures are required in tokamaks to get fusion started
What gas is exchanged into helium in a stars nuclear reactions?
In a star's nuclear reactions, hydrogen is converted into helium. This process, known as nuclear fusion, occurs in the core of a star, where high temperatures and pressures cause hydrogen atoms to combine to form helium.
What take an extremely high temperature for nuclear?
Nuclear fusion requires extremely high temperature and great pressure.
What is meant by nuclear reaction at very temperature?
there is no end-scale "highest" temperature, to put this in easy terms : the bigger the bang the higher the temperature, to answer the Question: the highest temperature would probably be the temperature created when the big-bang occurred.
What is a temperature of inner sun?
The temperature of the sun's core is estimated to be around 15 million degrees Celsius (27 million degrees Fahrenheit). This high temperature is necessary to sustain the nuclear fusion reactions that power the sun.
Does the onset of fusion reactions inside stars require high or low density and high or low temperature?
The onset of fusion reactions inside stars requires high density and high temperature. The high density is needed to bring atomic nuclei close enough together for the strong nuclear force to overcome electrostatic repulsion, allowing the nuclei to fuse. The high temperature is required to provide the particles with enough kinetic energy to overcome the electrical repulsion and fuse.
What has the author BSP Shen written?
B.S.P Shen has written: 'High-energy nuclear reactions in astrophysics' -- subject(s): Astrophysics, Nuclear reactions
What is the temperature of sun's inner core?
The temperature at the Sun's inner core is estimated to be around 15 million degrees Celsius. This high temperature is necessary to sustain the nuclear fusion reactions that power the Sun.
What is 1 condition necessary for nuclear reaction in the sun to occur?
Very high pressure at the centre due to gravity, and high temperature. Note however that temperature does not have to be so high as in tokamaks on earth, because the pressure and hence density of the plasma is so great.
Does nuclear fusion happen in the convection zone?
No, nuclear fusion does not occur in the convection zone of a star. Fusion reactions primarily take place in the core region of a star, where the temperature and pressure are high enough to sustain the nuclear reactions that power the star. The convection zone is a region of the star where heat is transported through the movement of gas, but fusion does not occur there.
What is the temperature of nuclear energy?
It does not have any particular temperature, the nuclear reactions are not influenced by temperature, though the behaviour of a nuclear reactor does depend on its temperature since this influences the neutron spectrum. In a PWR the coolant exit temperature is about 325 degC.
