Quizplus · Accepted Answer

When the two rods are placed in parallel, heat can flow through both the rods simultaneously. This means that the resistance to heat flow is reduced and more heat can be conducted compared to when the rods are in series. In the series arrangement, heat has to flow through the first rod before it can flow through the second rod. This increases the resistance to heat flow, resulting in less heat being conducted. Therefore, the heat conducted with the rods in series is less than the heat conducted with the rods in parallel.
