Question

One end of a metal rod is exposed to fire at a temperature of 547 °C while the other end remains at room temperature 22.7 °C. The rod length and radius are 1.48 m and 4.92 × 10-3 m, respectively. Calculate the amount of heat transferred from one end of the rod to the other in 6.00 s if we ignore the loss of heat over the length of the rod, and consider the thermal conductivity of the metal to equal 79 J/(s m Co).

Step 1

Given radius, \( r = 4.92 \times 10^{-3} \) m Area, \( A = \pi r^2 \) \( A = \pi \times (4.92 \times 10^{-3})^2 \) \( A = \pi \times 2.4216 \times 10^{-5} \) \( A = 7.61 \times 10^{-5} \) m² Show more…
