What is the temperature required for nuclear fusion to occur?
The temperature required for nuclear fusion to occur is around 100 million degrees Celsius.
Is the fallowing sentence true or false during nuclear reactions mass is not convserved but engery is conserved?
False. Both mass and energy are conserved during nuclear reactions, according to the principle of mass-energy equivalence stated by Einstein's famous equation, E=mc^2. This means that any changes in mass that occur during a nuclear reaction are accompanied by equivalent changes in energy and vice versa.
How a nuclear accident occur?
A nuclear accident can occur due to equipment failure, human error, or natural disasters. This can lead to the release of harmful radiation, posing serious risks to human health and the environment. Proper maintenance, training, and safety protocols are essential to prevent nuclear accidents.
Where does the reaction occur in nuclear fission?
Nuclear fission reactions typically occur in the core of a nuclear reactor. This is where the fissionable material, such as uranium-235, is bombarded with neutrons, causing the nuclei to split and release more neutrons and energy in a chain reaction.
What energy comes from changes in an atom's nucleus?
Nuclear energy comes from changes in an atom's nucleus, such as nuclear fission or fusion reactions. These processes release large amounts of energy in the form of heat and radiation.
How else are nuclear reactions unlike chemical reactions?
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
What is the study of changes that occur in atomic nuclei?
The study of changes that occur in atomic nuclei is known as nuclear physics. This field focuses on understanding the properties, behavior, and interactions of atomic nuclei, including processes such as nuclear decay, fission, and fusion. It plays a crucial role in various applications, including nuclear energy, medical imaging, and radiation therapy. Nuclear physics also contributes to our understanding of fundamental forces and particles in the universe.
What is the process by which the nucleus of an atom changes so that a new element is formed?
Nuclear transmutation is the process by which the nucleus of an atom changes, resulting in the formation of a new element. This can occur through radioactive decay, nuclear fission, or nuclear fusion, where the number of protons in the nucleus changes, leading to the creation of a different element.
What is the temperature required for nuclear fusion to occur?
The temperature required for nuclear fusion to occur is around 100 million degrees Celsius.
What is the decay process does radium 226 undergo including the nuclear changes that occur?
Radium-226--------------------Radon-222 + alpha
Do nuclear materials occur naturally?
Yes, that is where we get the nuclear material for our reactors, by mining it from the Earth. Though it does not occur in high concentrations, we have to concentrate it ourselves.
What causes the process of tansmutation?
Transmutation is caused by the rearrangement of atoms within a substance, leading to a change in its elemental composition. This can occur through processes like nuclear decay, radioactive decay, or nuclear reactions. Transformation of one element into another can also occur through artificial means in laboratories.
Why does nuclear fusion not occur on earth?
Because the conditions of temperature and pressure that occur in stars do not occur on earth
What nuclear changes occur when lithium forms in stars?
Lithium forms in the stars when the light nuclei are forced together and mix with yield energy. Because the mass of the combination will be less than the sum of the masses of the individual nuclei this will result to nuclear fusion.
Is the fallowing sentence true or false during nuclear reactions mass is not convserved but engery is conserved?
False. Both mass and energy are conserved during nuclear reactions, according to the principle of mass-energy equivalence stated by Einstein's famous equation, E=mc^2.

What are reflections that occur at changes in impedance?
Return loss refers to the reflections that occur at changes in impedance.
