## Question:

The thermal conductivity of a solid depends upon the solid’s temperature as k = aT + b where a and b are constants. The temperature in a planar layer of this solid as it conducts heat is given by

(a) aT + b = x + C_{2}

(b) aT + b = C_{1}x^{2} + C_{2}

(c) aT^{2} + bT = C_{1}x + C_{2}

(d) aT^{2} + bT = C_{1}x^{2} + C_{2}

(e) None of them
