Question

Consider two rods of the same length and different specific heats (S₁, S₂ ) , conductivities (K₁, K₂ ) and area of cross sections (A₁, A₂ ) and both having temperature T₁ and T₂ at their ends. If the rate of loss of heat due to conduction is equal then:

Quantrex Academy · Accepted Answer

Correct answer: A. K₁ A₁=K₂ A₂

Rate of conduction of heat is given as Q t = K A L (T₂-T₁ ) According to the question aligned & Q₁ t = Q₂ t & K₁ A₁ L (T₁-T₂ )= K₁ A₁ L (T₁-T₂ ) & K₁ A₁=K₂ A₂ aligned
