Ideal Gases

Step 1: Understanding the Partitioning of the Vessel
We are given that a vessel of volume L contains an ideal gas at temperature K. The vessel is then partitioned into two equal parts. Step 1: Understanding the effect of partitioning
When a vessel is partitioned into two equal parts, the volume of each part will be: Since no heat exchange occurs between the two parts after partitioning, the temperature remains the same. That is, Step 2: Verifying the correct answer
From the above calculations, the new volume in each partition is and the temperature remains . Hence, the correct answer is:
