20. Heat and the First Law of Thermodynamics
... Two bodies brought in thermal contact will change their temperature until they are at the same temperature. In the process of reaching thermal equilibrium, heat is transferred from one body to the other. Suppose we have a system of interest at temperature TS surrounded by an environment with tempera ...

Estimation of Atomic Mass from Specific Heat Data
... Before the development of mass spectrometry, it was difficult to determine the atomic mass of an element. In 1819, Dulong and Petit discovered that the product (about 26.4) of the atomic mass and the specific heat was nearly the same for many solid elements. This approximation has been found to be v ...
