Which of the following is (are) correct an adiabatic process?

In adiabatic process

Which of the following is not correct for adiabatic process ?

Which of the following is correct regarding adiabatic process

Which of the following is correct regarding adiabatic process (i) In adiabatic process, all the three variables, P, V and T changes (ii) In adiabatic process, the heat exchanged between system and surrounding is zero i.e., DeltaQ=0 (iii) Since DeltaQ=nCDeltaT , therefore for adiabatic process molar specific heat C=0 (iv) If a gas is suddenly expanded adiabatically temperature falls and if gas is adiabatically compressed, temperature rises
