Entropy of interaction in the nuclei

AI Thread Summary
The discussion centers on the complexity of understanding entropy in the interactions between protons, neutrons, and quarks, particularly in the context of nuclear fusion. It highlights that during fusion, nuclei transition to a lower energy state, releasing energy and increasing the system's entropy. The challenge lies in applying thermodynamic principles, such as the definition of entropy (ds = dQ/T), to nuclear reactions. The historical development of thermodynamics predates the understanding of atomic and subatomic structures, complicating the analysis. Overall, the conversation emphasizes the need for a deeper comprehension of entropy in nuclear interactions.

It's hard to me to understand about the interaction between protons and neutrons by the means of entropy. And Is it possible to know about an entropy of an interaction between protons and neutrons or between quarks:biggrin:?

Look at the case of Nuclear Fusion. When nuclei fuse, they go to a lower energy state and release energy in the process. Once this happens, it requires energy to break them apart. The entropy of the system has increased.

Thermodynamics was developed before anyone understood about atoms and molecules let alone sub-atomic structures. According to the thermodynamic definition of entropy, ds = dQ/T. Apply that to a system in which the source of heat flow is a nuclear reaction.

Thread 'Condensate rate of water for an air conditioning cooling coil'

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
