If two surfaces of area (A) distance (L) apart, of a material having thermal conductivity (mathrm{k}), are

Question:

If two surfaces of area $A$ distance $L$ apart, of a material having thermal conductivity $\mathrm{k}$, are at temperatures $t_{1}$ and $t_{2}$ then heat flow rate through it will be:

(a) $\mathrm{kA}\left(\mathrm{t}_{1}-\mathrm{t}_{2}\right) / \mathrm{L}$

(b) $\mathrm{LA}\left(\mathrm{t}_{1}-\mathrm{t}_{2}\right) / \mathrm{k}$

(c) $\mathrm{Lk}\left(\mathrm{t}_{1}-\mathrm{t}_{2}\right) / \mathrm{A}$

(d) None of these
