1.	If `DeltaU` and `Delta W` represent the increase in internal energy and work done by the system resectively in a thermodynamical process, which of the following is true?A. `DeltaU=-DeltaW`, in an adiabatic processB. `DeltaU=DeltaW`, in an isothermal processC. `DeltaU=DeltaW`, in an adiabatic processD. `DeltaU=-DeltaW`, in an isothermal process
Answer» Correct Answer - A From the first law of thermodynamics `Q=DeltaU+W` For adiabatic process `Q = 0` `implies DeltaU=-W`.
