The block in the drawing has dimensions L0 × 2L0 × 3L0, where L0 = 0.30 m. The block has a thermal conductivity of 250 J/(s ∙ m ∙ C°). In drawings A, B, and C, heat is conducted through the block in three different directions; in each case the temperature of the warmer surface is 35 8C and that of the cooler surface is 19 °C. Determine the heat that flows in 5.0 s for each case. |
