WebFor a temperature change at constant volume, dV = 0 and, by definition of heat capacity, d ′ QV = CV dT. (31) The above equation then gives immediately (32) for the heat capacity at constant volume, showing that the change in internal energy at constant volume is due entirely to the heat absorbed. WebParaffin, for example, has very large molecules and thus a high heat capacity per mole, but as a substance it does not have remarkable heat capacity in terms of volume, mass, or atom-mol (which is just 1.41 R per mole of atoms, or less than half of most solids, in terms of heat capacity per atom).

WebIn 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 (C P) to heat capacity at constant volume (C V).It is sometimes also known as the isentropic expansion factor and is denoted by γ for an … WebAlso (usefully for chemists), at constant pressure where is the enthalpy, so The specific heat capacity is the heat capacity per unit mass (or per mole). Heat capacities are not independent of temperature (or pressure) in general, but over a narrow temperature range they are often treated as such, especially for a solid.
