What is the temperature of an atomic nucleus?

“Temperature” is the differential relationship between entropy and internal energy, \begin{align} dU &= T\,dS + \cdots \\ \frac{\partial S}{\partial U} &= \frac 1T \end{align} where the ...

What is the temperature of an atomic nucleus?

A nucleus is a quantum system and has states in the same way an atom has states, though the states of nuclei are poorly understood compared to the states of atoms. We can assign a temperature to the ...

What is the temperature of an atomic nucleus?

Other answers correctly point out that since the energy-level spacing of a nucleus is large (of order MeV or tens of MeV), then unless the nucleus is in a very unusual environment, its state will ...

How can the temperature of the surroundings be constant during a reversible thermodynamic process?

This is an example of 2+2=5. First of all, not all reversible processes are isothermal. You have reversible isobaric, isochoric and adiabatic processes. For a reversible adiabatic process, the ...
