A thermally insulated container of volume V is divided into two equal parts by a thermally insulated partition. One part has N1 particles of a monatomic gas at temperature T1. The other has N2 at T2. The partition is now removed and the gases are allowed to mix. Find the final PRESSURE of the system and the CHANGE IN TOTAL ENTROPY if the gases are identical. 我可以翻译，不过这个应该不是很难懂，第一个求系统总压力，第二个求熵。还有2道类似的题，如果这道题会做，还能做出另外几道题我定有重谢。qq350913232 表明物理吧
