The contents of a well-insulated tank are heated by a resistor of 23$\Omega$ in which 10A current is flowing. Consider the tank along with its contents as a thermodynamic system. The work done by the system and the heat transfer to the system are positive. The rates of heat (Q), work (W) ad change in internal energy (DU), during the process in kW are
(a) Q=0, W=–2.3,$\Delta$U = +2.3
(b) Q= +2.3, W = 0, $\Delta$U= +2.3
(c) Q = 2.3, W=0, $\Delta$U= –2.3
(d) Q=0, W= +2.3, $\Delta$U= –2.3
