A well machined steel plate of thickness $$L$$ is kept such that the wall temperature are $${T_h}$$ and $${T_c}$$ as shown in the figure below. A smooth copper plate of the same thickness $$L$$ is now attached to the steel plate without any gap as indicated in the figure below. The temperature at the interface is $${T_i},$$ The temperature of the outer walls are still the same at $${T_h},$$ and $${T_c}.$$ The heat transfer rates are $${q_1}$$ and $${q_2}$$ per unit area in the two cases respectively in the direction shown. Which of the following statements is correct? GATE PI 2005 Heat Transfer - Conduction Question 5 English
A
$${T_h} > {T_i} > {T_c}$$ and $${q_1} < {q_2}$$
B
$${T_h} < {T_i} < {T_c}$$ and $${q_1} = {q_2}$$
C
$${T_h} = \left( {{T_i} + {T_c}} \right)/2$$ and $${q_1} > {q_2}$$
D
$${T_i} < \left( {{T_h} + {T_c}} \right)/2$$ and $${q_1} > {q_2}$$
