1. The problem statement, all variables and given/known data Two bars are placed between plates whose temperatures are Thotand Tcold . The thermal conductivity of bar 1 is six times that of bar 2 (k1 = 6k2), but bar 1 has only one-third the cross-sectional area (A1=1/3 A2 ). Ignore any heat loss through the sides of the bars. Which statement below correctly describes the heat conducted by the bars in a given amount of time? 2. Relevant equations 3. The attempt at a solution Bar 1 conducts twice the heat as does bar 2; Q1 = 2Q2 is the answer but how??
