Find the heat that flows in 1.0 s through a lead brick 13 cm long if the temperature difference between the ends of the brick is 8.0â°c. the cross-sectional area of the brick is 13 cm^2. express your answer using two significant figures.

Explanation:

Heat transfer due to conduction is given by the formula

here we know that

A = area of crossection

L = length through which heat will flow

= temperature difference across the ends of rod

K = thermal conductivity = 35 W/m K

now from above formula we can say

this would be about 43%
