    This question is with regards to the heat transfer through conduction.

    Heat Current means Total heat energy liberated per second.

    Go for the formula:


    Where Q/t=heat current

    dT=difference in temeperatures on both side of the walls(140 in the question)

    K=Thermal conductivity=0.04 (given)

    A=Area of the cross section

    x=length of the cross section
