1.	During an adiabatic reversibly expansion of an ideal gasA. Internal energy of the system decreases.B. Temperature of the system decreases.C. The value of `gamma` changesD. Pressure increases.
Answer» In adiabatic process, `q = 0`. Hence, in expansion process, temperature decreases and hence internal enegry also decreases.
