1.	If Delta U 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» `DELTA U = -Delta W`, in a ADIABATIC PROCESS `Delta U = Delta W`, in isothermal process `Delta U = Delta W`, in a adiabatic process `Delta U = -Delta W`, in a isothermal process Answer :A
