    Absorbing heat means that heat energy is accumulating in the mass/material. Conducting heat simply means that heat is moving into or through the material, but it does not imply that heat is accumulating.

    If there is a temperature difference between ends or sides of the rod, the heat will move (be conducted) through the rod, but the internal energy will not necessarily increase, especially if the boundary conditions (temperatures) are constant.
