Question

Does the second law of thermodynamics apply to a single electron in deep space? Or two electrons? Or 100? (assume the electrons are restricted in a finite area)

From which point we can start to talk about the entropy of a closed system?

Answer 1

The second law of thermodynamics applies to any system, including a single electron in deep space.

Step-by-step explanation:

The second law of thermodynamics states that the entropy of a closed system either remains the same or increases in every process. Entropy, which is a measure of disorder, is closely related to the second law of thermodynamics. Therefore, the concept of the second law and the increase in entropy applies to any system, regardless of the number of electrons involved. So, whether it is a single electron, two electrons, or 100 electrons in deep space, the second law of thermodynamics still applies.
