Q.

A heat source at T= l03 K is connected to another heat reservoir at T=102 K by a copper slab which is 1 m thick. Given that the thermal conductivity of copper is 0.1 WK–1 m–1, the energy flux through it in the steady state is :

  1. A

    90 Wm–2 

  2. B

    200 Wm–2

  3. C

    65 Wm–2

  4. D

    120 Wm–2
