Compare the difference between Rhythmic and rhythm

Rhythms is while rhythm is the variation of strong and weak elements such as duration accent of sounds notably in speech or music over time a beat or meter

Lower temperatures favor Coble creep and higher temperatures favor Nabbaro–Herring creep because the activation energy for vacancy diffusion within the lattice is typically larger than that along the grain boundaries, thus lattice diffusion slows down relative to grain boundary diffusion with decreasing temperature.
