Einstein temperature of diamond
WebQuestion: problems 4.7 The Debye temperature of the diamond is 1860 K and the Einstein temperature is 1450 K. Experiments on the diamond its specific heat is T 207 … WebThe Stokes-Einstein Relation Albert Einstein realized that an ion moving in an electrolytic solution is somewhat analogous to a macroscopic sphere moving in a liquid medium. A macroscopic sphere can travel very fast if it is outside of water or any other liquid; however, its velocity will definitely be affected if it is put in some liquid.
