AP Physics 2
9.5 Specific Heat and Thermal Conductivity
An engineer evaluates two rectangular insulation panels, Panel 1 and Panel 2, for an exterior building wall. Both panels have identical cross-sectional area \(A\) and are subjected to the same temperature difference \(\Delta T\) between their opposite faces.
Which row in the table correctly compares the rate of thermal energy transfer \(P_2\) through Panel 2 and the time \(\Delta t_2\) required to transfer a fixed quantity of thermal energy \(Q_0\) through Panel 2 to the corresponding values for Panel 1?
| Panel | Thermal Conductivity | Thickness |
|---|---|---|
| 1 | \(2k_0\) | \(L_0\) |
| 2 | \(k_0\) | \(2L_0\) |
Which row in the table correctly compares the rate of thermal energy transfer \(P_2\) through Panel 2 and the time \(\Delta t_2\) required to transfer a fixed quantity of thermal energy \(Q_0\) through Panel 2 to the corresponding values for Panel 1?
