A container of volume 1 m3 is divided into two equal parts by a partition. One part has an ideal diatomic gas at 300 K and the other part has vacuum. The whole system is isolated from the surrounding. When the partition is removed, the gas expands to occupy the whole volume. Its temperature will be
Options:
Answer:
A
Solution:
Free expansion into vacuum: W = 0 (no external pressure) and Q = 0 (isolated), so Δ U = 0. For an ideal gas U depends only on T, so T stays 300 K. Matches (a).
