An ideal gas is compressed reversibly in a perfectly insulated cylinder (). Its temperature will

  1. Adecrease
  2. Bremain constant
  3. Cfirst decrease and then increase
  4. Dincrease

Answer: D

In an adiabatic process , so . Compression makes , hence and, for an ideal gas, the temperature rises.
