Show that use of the energy theorem (Problem 2) in the Lagrangian integral form of conservation of energy, d dt Vo 1 2 v · v + ε rhoo dVo = Vo (b · v + r) rhoo dVo + So (to · v − qo · no) dAo, leads to the pointwise (differential) form: rhoo ε˙ = To · ˙F + rhoo r − Div qo, where qo is the referential heat flux vector.
