Web13 de ene. de 2024 · Einstein's theory also explains solids that exhibit a low heat capacity even at relatively high temperatures. An example of such a solid is diamond. The heat capacity of diamond approaches 3 N k as temperature greatly increases. Einstein's model supports this through the definition of an Einstein temperature. http://www-personal.umich.edu/~kaviany/researchtopics/HTP%20Objective.pdf

WebThe molar heat capacity does not decrease with temperature as rapidly as suggested by Einstein's model because these long-wavelength modes are able to make a significant contribution to the heat capacity, even at very low temperatures. A more realistic model of lattice vibrations was developed by the Dutch physicist Peter Debye in 1912. WebHace 2 días · The temperature dependence (at constant volume) of the heat capacity of a solid (in J mol − 1 K − 1) can be described by the Einstein model.
