Can you identify a physical situation when the partial derivatives from the left and right are not the same?
What will be an ideal response?
Often at a boundary between two different conduction materials the left and
the right gradients could be different. Another situation could be if radiation or
convection heat transfer occurs at a boundary and then again the left and right
gradients or derivatives could be different.
