WebThus, the Joule coefficient for a van der Waals gas is negative. This implies that the temperature of the gas always decreases as it undergoes free expansion. Of course, this temperature decrease is a consequence of the work done in overcoming the inter-molecular attractive forces. WebThe global stability is determined by investigating the Gibbs free energy of the system. For this RN-AdS black hole immersed in PFDM, the Gibbs free energy can be calculated as (16) G = M − T S = v 8 − π v 3 12 P + 3 Q 2 2 v − λ 4 + λ 2 ln v 2 λ.
