1.	If DeltaU and Delta W represent the increase in internal energy and work done by the system respectively in a thermodynamical process, which of the following is true?
Answer» `DeltaU=-DeltaW` in an ADIABATIC PROCESS `DeltaU=DeltaW` in an ISOTHERMAL process `DeltaU=DeltaW` in an adiabatic process `DeltaU=-DeltaW` in an isothermal process Answer :A
