| Sep 17 at 10:10 | comment | added | Buck Thorn♦ | What is the entropy of a single particle? And why can't changes in the energy of a particle be reversed? You might want to be more clear about the system you are referring to. Note also this is chem SE, phys SE might be more appropriate for cosmological questions. | |

| Sep 15 at 6:55 | comment | added | Poutnik | CPT is the only combination of C, P, and T that is observed to be an exact symmetry of nature at the fundamental level. | |
| Sep 15 at 6:54 | comment | added | user146560 | Well its my wrong it would have been CP,T symmetries . Since T(reversal symmetry) is violated when CP violations occur @Poutnik | |
| Sep 15 at 6:52 | comment | added | user146560 | @PaulKolk I surely mean here Closed system , since no matter exchange concept was included in my qn | |
| Sep 15 at 6:50 | comment | added | user146560 | @Poutnik yeah I didnt include the breaking of CPT symmetry which occur under weak interactions here | |
| Sep 15 at 6:33 | comment | added | Paul Kolk | Open systems are not composed of fixed amount of particles. Closed systems of macroscopic size are too complex to describe particle-by-particle. | |
