Que. A plane slab of thickness 60 cm is made of a material of thermal conductivity k = 17.45 W/m K. Let us assume that one side of the slab absorbs a net amount of radiant energy at the rate q = 530.5 watt/m². If the other face of the slab is at a constant temperature t₂ = 38 degree Celsius. Comment on the temperature with respect to the slab?
a. 87.5 degree Celsius
b. 32 degree Celsius
c. 47.08 degree Celsius
d. 32.87 degree Celsius
