  1. It increases

  2. It decreases

  3. It may increase or decrease

  4. It will remain unchanged

B Correct answer
Explanation

The adiabatic (no heat exchanged) expansion of a gas may be carried out in a number of ways. The change in temperature experienced by the gas during expansion depends not only on the initial and final pressure, but also on the manner in which the expansion is carried out. If the expansion process is reversible. The gas does positive work during the expansion, and its temperature decreases.
