Consider the given diagram. An ideal gas is contained in a chamber (left) of volume \(V\) and is at an absolute temperature \(T\). It is allowed to rush freely into the right chamber of volume \(V\) which is initially vacuum. The whole system is thermally isolated. What will be the final temperature of the equilibrium has been attained?

  1. A \(T\)
  2. B \(\frac{T}{2}\)
  3. C \(2 T\)
  4. D \(\frac{T}{4}\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(T\)

Step-by-step Solution

Detailed explanation

Since, the whole system is isolated, this means, there is no transfer of heat between the system and the surrounding. Also, the right side container is initially vacuum, so the gas could easily rush there without any resistive force. As the right side container has no…
