Question

Two rods having same length and cross-sectional area are connected individually between temperature $T_1$ and $T_2$. If the rate of loss of heat due to condution is equal and specific heat of two rods are in the ratio $1:2$, then the ratio of their thermal conductivity will be

• A. $1:1$
• B. $1:2$
• C. $2:1$
• D. $1:\sqrt{2}$

Answer 1

The correct option is A $1:1$

Thermal conductivity of a material does not depend upon the specific heat capacity.
$\therefore$ For same length and area of cross-section.
$\frac{k_1}{k_2}=1$
