Energy balance for a closed system can be defined as: The change

Energy balance for a closed system can be defined as: The change in the amount of energy contained within a closed system during some time interval is always equal to zero; ensfar The change in the amount of energy contained within a closed system during some time interval is equal to the net amount of energy transferred in and out across the system boundary by heat only during the time interval; The change in the amount of energy contained within a closed system during some time interval is impossible; The change in the amount of energy contained within a closed system during some time interval is equal to the net amount of energy transferred in and out across the system boundary by work only during the time interval. The change in the amount of energy contained within a closed system during some time interval is equal to the net amount of energy transferred in and out across the boundary by heat and work during the time interval; system I don't know
