हिन्दीTwo cylinders A and B of equal capacity are connected to each other via a stop cock. A contains an ideal gas at standard temperature and pressure. B is completely evacuated. The entire system is thermally insulated. The stop cock is suddenly opened. The process is:
Correct answer · Option 1
adiabatic
Explanation
Free expansion into vacuum is thermally insulated and involves no work done, hence it is an adiabatic process.
