Heat is carried along or through a material being transferred along from molecule to molecule through collisions; this form of heat transfer is conduction.
The conduction heat transfer rate is proportional to the difference in temperature between the two sides of the conducting medium.
Hcond = heat-transfer rate for conduction
K = thermal conductivity which depends upon the material
K is large for a good heat conductor.
K is small for a good insulator.
A = cross-sectional area
L = length
T1 and T2 are the temperatures of the two regions a distance L apart.
