I wonder how one can explain the heat generated from the physical point of view, i.e. in terms of fields and electric potentials of the chemical bonds

Good Morning, is it possible to get a physical model, I think to electromagnetic fields, to explain the energy developed in exothermic reactions es. for the hydration of sulphuric acid? thank you

good morning, I read that are defined two type of 'velocities' in Special relativity: ordinary v1= dl/dt where l and t are measured in ground-based frame proper v2= dl/d(tau), a hybrid quantity where l is the same as ordinary v1 but tau is the proper, rest time I can't understand the...

good morning Sirs, in my special-relativity texbook i read that, for a generic mass particle system, with respect to a particular frame where the total system linear momentum is zero the mass-energy relation will have a simple, well known and 'satisfactory' form. Well: what is this frame? its...

good morning, I'd like to know if exsists a classical explanation and, of course, qualitative about the nuclear fission / fusion reactions. I would like to explain the development of external energy to considering only nuclear forces system in terms of internal mechanical energy and the fact...
