Two bars are conducting heat from a region of higher temperature to a region of lower temperature. The bars have identical lengt

inna [3103]

Answer:

Arrangement A facilitates a greater rate of heat transfer

Explanation:

The rate of heat conduction between two materials differing in temperature adheres to the formula

$\frac{\Delta Q}{\Delta t}=\frac{-KA \Delta T}{ L}$

This equation demonstrates that

An enlarged equivalent cross-sectional area between the two materials will enhance the rate of heat transfer.
A reduction in the length of the medium will also amplify the rate of heat transfer

Arrangement A features a shorter transfer medium and a larger equivalent cross-sectional area, since the two rods are set up in a parallel arrangement.

Conversely, Arrangement B has a longer transfer medium and a smaller cross-sectional area, as the two rods are placed end to end
