... where in case of pure mechanical interactions the V (volume), T (temperature) and N (particle number) are fixed. This means that we consider a closed system in contact with a heat-bath at temperature T. Due to the heat-exchange with the heat reservoir the energy can fluctuate. We learn from thermody ...
