Specific heat Definition & Meaning - Merriam-Webster

WebDuring an endothermic reaction energy or heat is absorbed to decrease the temperature of the surroundings. Cold packs that are used to reduce swelling often use chemicals that when mixed produce an endothermic reaction. Under constant pressure the heat of the reaction is equal to the enthalpy change for the reaction (ΔHΔ). In thermal physics and thermodynamics, the heat capacity ratio, also known as the adiabatic index, the ratio of specific heats, or Laplace's coefficient, is the ratio of the heat capacity at constant pressure (CP) to heat capacity at constant volume (CV). It is sometimes also known as the isentropic expansion factor and is denoted by γ (gamma) for an ideal gas or κ (kappa), the isentropic exponen… cornell university ranking 2023 https://0800solarpower.com
