A rigid insulated container of volume 2 m3 is divided into two equal parts by a partition. One part has an ideal monoatomic gas at 400 K and the other part is evacuated. When the partition is removed, the gas expands to occupy the whole volume. Its final temperature will be
Options:
Answer:
D
Solution:
Free expansion into vacuum: W = 0, and Q = 0 (insulated), so Δ U = 0. For an ideal gas U depends only on T, so T stays 400 K = 127°C. Matches (d).
