Thermodynamics Ques 3
3. 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 :
[2020]
(a) adiabatic
(b) isochoric
(c) isobaric
(d) isothermal
Show Answer
Answer:
Correct Answer: 3.(a)
Solution: (a) Entire system is thermally insulated. So, no heat exchange with surrounding will take place. Hence, process will be adiabatic.
