Question

Quizplus · Accepted Answer

The heat conduction through a rod is directly proportional to the cross-sectional area (πr²) and inversely proportional to its length (l). A larger radius and shorter length will conduct more heat. Option B has the largest radius and the shortest length among the given options.
