Two bars, A and B, each of length 2.0 m and cross-sectional area `10m^(2)`, are placed and to end as shown in the figure.
The thermal conductivities of the bars are `k_(A) = 339 ( J //s. m.K)` and `k_(B) = 837 J//(s.m.K)`, respectively. The left end of bar A is maintained at 373 K while the right end of B is maintained at 273 K

Which one of the following statements is true concerning the above situation ?

A

For a given time l, the amount of heat transferred through bar A is the same as that through B.

B

For a given time l, the amount of heat transferred through bar A is smaller than that through B.

C

For a given time t, the amount of heat transferred through bar A is less than that through B.

D

The time for a quantity of heat Q to pass through bar A is less than that for B.
