How is the energy content in 1 kg of water and petrol the same?
We know petrol is a fuel and water is not. But how come 1 kg of water and 1 kg of petrol have the same energy content? The total energy is given by $E=mc^2$, it says nothing about the chemical ...

Nuclear fusion kinetic energy nucleons theory
Is this theory correct?
I got this theory from a nuclear fusion expert in stack exchange and he told me to confirm it here...
The theory:
When two nuclei come closer enough (due to external energy ...

Tightly bound energy configuration for nucleons?
In fusion, why are nucleons of the product nucleus tightly bound and in a lower energy configuration than the nucleons in the reactant nuclei? I think the reason a large amount of energy is released ...

Nuclear fusion mass defect and energy production
In researching the topic of nuclear fusion, I have a few doubts related to the mass defect, 'negative' potential energy and resultant energy released as a by-product of nuclear fusion.
When two ...

Internal energy bound configuration in nuclear fusion [closed]
I have read that
when a reaction occurs in which the products of the reaction are in a
less energetic state than the reactants, the kinetic energy of the
products is increased over that of the ...

Nuclear FISSION origin
Neutrons and protons consist of quarks, and when a neutron and a proton are squeezed tightly enough together, the quarks in each begin to interact and cause them to attract one another. The resulting ...

Energy turns into mass [closed]
I studied on YouTube that when mass is converted into energy, energy is converted into mass somewhere, but when I searched for this theory, I did not find it. Does anyone know what the name of this ...

How can the products of a higher energy fusion reaction be heavier?
I was told the mass defect of an atom is the difference in mass of the atom versus it's particles, for example:
carbon 12 is less massive than 6 protons + 6 neutrons + 6 electrons.
this negative ...

Mass energy equivalence, binding energy and chemical reactions [duplicate]
I recently was nuclear physics there I learned that the the actual mass of a nucleus is less than what we expect it to be (simply adding the masses of the nucleons). It is due to the release of ...

What is more massive, Proton, standard Hydrogen?
If you consider the classical states of hydrogen, one in which the electron is rotating at an orbital distance of $r$ and then take $\lim_{r\to\infty}$ one obtains that the $r_\infty$ state has more ...

How does Pauli exclusion principle cause the coupling term in Weizsäcker formula?
Consider the pairing term in Weizsäcker formula. Here it is claimed that:
Due to the Pauli exclusion principle the nucleus would have a lower
energy if the number of protons with spin up were ...

Rest mass of the nucleus and its constituent nucleons
One of the question in my book says that if $E$ denote the rest mass energy of a nucleus and $n$ a neutron then,
a.) $E(U^{236}_{92})>E(I^{137}_{53})+E(Y^{97}_{39})+2E(n)$
b.)$E(U^{236}_{92})<...
