A container of volume is divided into two equal compartments by a partition. One of these compartments contains an ideal gas at . The other compartment is vacuum. The whole system is thermally isolated from its surroundings. The partition is removed and the gas expands to occupy the whole volume of the container. Its temperature now would be
View answer and explanation
Correct option: A
Option A is correct because the expansion is a free expansion into a vacuum, and since the system is thermally isolated, no work is done and the temperature remains constant.
