  • Rule of Dulong and Petit

    C17-5 Most solid specimen with monatomic elementary entities have a molar heat capacity $\approx 25 \text{ J/mol K} = 3R$ with the gas constant.

  • heat capacity as a result of molecules

    C18-4 Because molecules are always in motion, thermal energy and kinetic energy are fungible, we can take a statistical mechanics approach.

  • isochorically

    C18-4 For a given specimen, constant volume through a state change. Canonical Hub: CANONICAL_INDEX.

  • crystal

    C18-4 A solid with elementary entities with definite size and a definite shape, within a material system exhibiting intermolecular long-range order.

  • principle of equipartition of energy

    C18-4 That the energy capacity of intramolecular motion is balanced evenly across permissible degrees of freedom.

  • quantum mechanics

    C18-4 While relativity describes phenomena involving very large momentum, smaller momentum phenomena such as the atom, nucleus begin to exhibit behavior as a wave, such as the relationship between the photon and electromagnetic waves and light.

  • intramolecular motion

    C18-4 statistical mechanics leads to the following important results principle of equipartition of energy degrees of freedom … in a monatomic ideal gas In the scope of intramolecular motion, for a monatomic gas, the number of velocity components needed to completely describe the motion.

  • diatomic vibration

    C18-4 This degrees of freedom does not contribute to heat capacity and specific heat effectively, due to Quantum Mechanics: kinetic energy due to such motion is quantized, can only change in finite steps — there is a “first step” whereby there is no motion Call this step size [$\Delta E$ → When we r...

  • concentration

    C18-4 A physical quantities that appears in semiconductors, and Thermodynamics more generally.
