An attempt has been made to discuss the classical topic of statistical physics so called the microscopic dynamics and derive the equilibrium thermodynamics which describes a macroscopic system. Here, we try to explain the microscopic theory is the term of quantum chromo-dynamics (QCD), and we want to obtain the thermodynamics of strongly interacting matter. Finally, at this point we notice that two basic features of what we're about to study-the equilibrium condition and the arbitrarily large
