As we know the thermodynamic quantities such as entropy and extremal bounds of black holes play an important role in general relativity. On the other hand, such quantities are changed by the perturbative corrections. In this paper we take advantage from such corrections and obtain the universal relations between the entropy and extremal bound of black hole. In this way perturbative corrections for the entropy is positive and the mass of extremal black hole is decreasing. Also we take the corresponding perturbative corrections and investigate the universal relation such as entropy and the extremal bounds for the different black holes. Finally, we see that the extremality relation of the black holes have a similar behaviour to the Weak Gravity Conjecture $\left(WGC\right)$.

众所周知，黑洞的熵和极值边界等热力学量在广义相对论中起着重要作用。另一方面，这些量通过微扰校正而改变。在本文中，我们利用这种校正的优势，获得了熵与黑洞极值边界之间的通用关系。这样，对熵的摄动校正为正，并且极端黑洞的质量在减少。同样，我们采取相应的摄动校正，并研究诸如黑洞的熵和极值边界的普遍关系。最后，我们看到黑洞的极端关系与弱重力猜想具有相似的行为。$（\mathrm{w\; ^}GC）$。
