Answer #1

Q = T1 - T2 / R

where,

R is thermal resistance

Q = T1 - T2 / (L / KA)

R = L / KA

R = L (KA)-1

Ans B

    PLEASE ANSWER a,b,c Heat Conduction Heat conduction occurs through any material, represented here by a rectangular bar, whether window glass or walrus blubber. The temperature of the material is T2 on the left and T1 on the right, where T2 is greater than T1. The rate of heat transfer by conduction is directly proportional to the surface area A, the temperature difference T2 - T1, and the substance's conductivity k. The rate of heat transfer is inversely proportional to the...
