WebThe specific heat capacity is defined as the quantity of heat (J) absorbed per unit mass (kg) of the material when its temperature increases 1 K (or 1 °C), and its units are J/ (kg K) or J/ (kg °C). From: Experiment and Calculation of Reinforced Concrete at Elevated Temperatures, 2011 View all Topics Add to Mendeley About this page WebJan 30, 2024 · For ordinary solids at or above room temperature, the molar heat capacity is approximately the same ( Dulong and Petit's law ), three times the gas constant, about 25 J/K. It is because the sum of potential and kinetic energy per atom is 3 k B T in the harmonic approximation. Hydrogen in water or ice is a bit different. ready sign in https://drogueriaelexito.com
