Question

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 :

Answer 1

Correct option is A. adiabatic

Hint: A thermodynamic process that happens without transmitting heat or mass between the thermodynamic system and its surroundings is known as an adiabatic process.

Correct Answer: Option A

Explanation of Correct Answer:

The entire system is entirely insulated, allowing for free gas expansion while maintaining a steady gas temperature.

As a result, the procedure will be adiabatic.

So, the correct answer is option (A).

Explanation of Incorrect Options:

There should be no change in volume for isochoric process, but there change in volume exist. So, Option (B) is incorrect.

There should be no change in pressure for isobaric process, but there change in pressure exist. So, Option (C) is incorrect.

There is exchange of Heat by maintaining constant Temperature in isothermal process, but there is no exchange in heat .So, Option (D) is incorrect.

Therefore, Option (B), Option (C) and Option (D) are incorrect. The correct answer is option (A).
