Which of the following statements are true?Select one or more:a)Chemic...
A massive ideal gas with only one type of particle is uniquely described by three state functions such as temperature, volume and number of particles. However for a black body, the energy distribution is established by interaction of photons with matter, usually walls of container. In this interaction, number of photons is not conserved. As a result, chemical potential is zero.
Further (b) and (c) are basic facts about the chemical potential and hence are true.
The correct answers are: Chemical potential for photon is zero, In phase equilibrium, total sum of chemical potentials is zero, Chemical potential of electron at zero Kelvin is same as Fermi Energy.
