Question

The lengths of two rods made of the same metal and having the same area of cross-section are 0.6 m and 0.8 m. The temperatures of the ends of the first rod are 9 0 ∘ C and 6 0 ∘ C, and for the second rod are 15 0 ∘ C and 11 0 ∘ C. For which rod is the rate of conduction greater?

TestHub · Accepted Answer

The rate is K A × L Δ T ​ . First rod: 0.6 30 ​ = 50 . Second rod: 0.8 40 ​ = 50 ∘ C m − 1 . Equal. C.
