The flow and heat transfer of a power-law fluid over an unsteadily stretched surface with variable thermal conductivity is studied. The governing equations are reduced to a class of non-linear ordinary differential equations by means of similarity transformations and an approximate analytical solution is obtained by using a modified homotopy perturbation method. The effects of the various parameters (power-law index, unsteadiness parameter, Prandtl number and variable thermal conductivity) on the velocity and temperature fields are graphically illustrated and analyzed.
