Heat Conduction Law
The material time derivative of the kinetic plus internal energies is equal to the sum of the rate of work of surface and body forces, plus all other energies that enter or leave the body per unit time. Other energies include, thermal, electrical, magnetic or chemical.
U = Internal Energy
K.E. = Kinetic Energy
Qc = Net heat due to conduction
Qs = Net heat due to radiation
P = Rate of work done (mechanical)
