1.	In an adiabatic process, no transfer of heat takes place between system and surroundings.Choose the correct option for free expansion of an ideal gas under adiabatic condition from the following.
Answer» `q = 0, DeltaT ne 0, w = 0` `q ne 0 , Delta T = 0 , w = 0` `q = 0, DeltaT = 0 , w = 0` `q = 0, DeltaT LT 0, w ne 0` Solution :Work done in FREE expansion of an ideal gas is ZERO. `THEREFORE w = 0` Also, in an adiabatic process, q = 0 `therefore DeltaU = q + w = 0`. This MEANS that during the process, `DeltaU` remains constant.Therefore, during expansion no change in temperature takes place. `therefore DeltaT = 0`
