The fact that a refrigerator requires energy to move heat from a colder object (the inside of the refrigerator)to a hotter object (the outside of the refrigerator)is a real life observation of which law of thermodynamics?

Question

This observation is a real-life example of the second law of thermodynamics, which states that in any energy transfer or transformation, the total entropy (disorder) of a closed system always increases over time. In the case of a refrigerator, energy is needed to transfer heat from a colder object to a hotter object, which increases the entropy of the system overall.
