Chapter 13, Problem 1FC

To determine

The depending factors of heat conducted through a bar.

Answer to Problem 1FC

The correct option is “(d) B, D, and E”.

Explanation of Solution

Formula used:

Write the expression for conducted heat $\left(Q\right)$.

$Q=\frac{\left(kA\Delta T\right)t}{L}$ . (1)

Here

k is thermal conductivity of material,

A is cross-section area,

$\Delta T$ is temperature difference between the ends, and

L is length.

Explanation:

From equation (1), the conducted heat depends on the thermal conductivity of material, length or thickness of bar, temperature difference, surface area and time. From the given choice of options B, The thermal conductivity, D. The length of the bar, and E. The cross-section area of bar are true depending factors of the conducted heat.

Conclusion:

Thus, the correct option is “(d) B, D, and E”.
