A resistor held in running water carries
electric current. Treat the resistor as
the system (a) Does heat flow into the
resistor? (b) Is there a flow of heat
into the water? (c) Is any work done?
(d) Assuming the state of resistance to
remain unchanged, apply the first low of
thermodynamics to this process.

Unless there are extenuating circumstances such as a fan, breeze etc. that can move heat, heat flows from hot to cold… This makes sense because cold has less heat than hot so it cant give off any heat… Is the resistor or the water the hottest…? Yes, there is work being done. or

Running water will be a less resistant path rather than flowing through resistor. So heat produced will be almost zero.
