Thermal Conductivity Comparison
AP Physics 2 · Unit 9 Thermodynamics
Learning Objectives
Fourier's Law: Q/t = kAΔT/L
Compare metals vs insulators
Understand conductivity k (W/m·K)
Heat flow rate depends on k, A, ΔT, L
Fourier's Law
Q/t = kA(T_hot − T_cold)/L
k = thermal conductivity
A = cross-section area
L = length
