... (d) What are the limiting values of the entropy as T → 0 and as T → ∞ ? How would your results change if it was a spin-1/2 particle? In the limit T → 0 (or B → ∞ ), only the lowest (ground) state is occupied. The multiplicity of the ground state is Ω = 1 . Therefore, S = k B ln Ω → 0 In the limit T ...

Work-Energy Theorem
... Introduction The Work-Energy Theorem states that the work done on a body by an external force is related to the resulting change in kinetic (K) and/or potential (U) energy. Work = ΔK + ΔU When a spring is disturbed from its equilibrium position, it's potential energy is determined by Us = ½ kx2 wher ...

Heat transfer physics
Heat transfer physics describes the kinetics of energy storage, transport, and transformation by principal energy carriers: phonons (lattice vibration waves), electrons, fluid particles, and photons. Heat is energy stored in temperature-dependent motion of particles including electrons, atomic nuclei, individual atoms, and molecules. Heat is transferred to and from matter by the principal energy carriers. The state of energy stored within matter, or transported by the carriers, is described by a combination of classical and quantum statistical mechanics. The energy is also transformed (converted) among various carriers.The heat transfer processes (or kinetics) are governed by the rates at which various related physical phenomena occur, such as (for example) the rate of particle collisions in classical mechanics. These various states and kinetics determine the heat transfer, i.e., the net rate of energy storage or transport. Governing these process from the atomic level (atom or molecule length scale) to macroscale are the laws of thermodynamics, including conservation of energy.
