A metal rod of length L and cross-sectional area A connectstwo thermal reservoir

Question

A metal rod of length L and cross-sectional area A connectstwo thermal reservoirs of temperatures T1 and T2. The amountof heat transferred through the rod /unit time is directlyproportional to a. A and L b. A and 1/L c. 1/A and L d. 1/A and l/L e. A and L 2 Explain answer A metal rod of length L and cross-sectional area A connectstwo thermal reservoirs of temperatures T1 and T2. The amountof heat transferred through the rod /unit time is directlyproportional to a. A and L b. A and 1/L c. 1/A and L d. 1/A and l/L e. A and L 2 Explain answer Explain answer

Explanation / Answer

Heat transfer through rod per unit time            Q / t    = k A (TH -TC )   / L                        from the above equation                       Q / t is directly proportional to A and 1/ L So Answer is    : b
