AIPMT PRELIMS 2002 Physics Heat Transfer MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Consider two rods of 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 rate of loss of heat due to conduction is equal, then :-
A
K₁A₁ = K₂A₂
B
K₁A₁/S₁ = K₂A₂/S₂
C
K₂A₁ = K₁A₂
D
K₁A₁/S₂ = K₁A₂/S₁
Correct Answer
Option A
Detailed Explanation
The rate of heat conduction is given by Fourier's law, which depends on the product of thermal conductivity and area.
