Q.
Two 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 :
A) adiabatic
B) isochoric
C) isobaric
D) isothermal
Explanation
[Solution] The system is thermally insulated (no heat exchange), so the free expansion is adiabatic. Answer (1).
