15:00 for those of u wondering how gas cools on expansion: Here, against the norms, gas does the work(work done by the system) and loses some part of its energy.thus, it cools.(below inversion temperature as one of the commenters mentioned).

[@piyushkala9707]

U can also say that it's internal energy decrease and temperature is directly proportional to∆U hence temp fall

[@radhikavij2760]

But it is not always.. only below inversion temperature .. so it is technically wrong
