APFIVE Temperature Dependence of Thermal Conductivity
Two metal rods with identical dimensions are tested at different temperatures. Scientists observe that as temperature increases from 20°C to 80°C, the thermal conductivity of rod A decreases while rod B’s increases. What best explains this difference?
A
Rod B has a higher melting point than rod A
B
Temperature cannot affect intrinsic thermal conductivity
C
Different dominant heat transfer mechanisms at atomic level
D
Rod A’s specific heat must be greater than rod B’s
