Enthalpy
Why does the magnitude in the change in entropy depend on temperature when heat is transferred?

Re: Enthalpy
Entropy=enthalpy/temperature so since temperature is in the denominator the higher the temperature is the less entropy will be.

Re: Enthalpy
Entropy is defined as ΔS=q/T. Based off the equation, the magnitude of change in entropy is greater when the value of T is lower. This is because temperature is in the denominator so the heat added to the system will have a greater effect on the change in entropy.
Thinking about it intuitively, this makes sense because adding heat to a system increases the system's total energy. This gives more kinetic energy to the particles in the system. Thus, increasing the entropy of the system. So, if the system starts at a lower temperature, adding heat will have a larger effect on ΔS.

Re: Enthalpy
Delta S=q/T so since temperature is the denominator, if you make T bigger, delta S will be smaller and vice versa, if you make T smaller, delta S will be bigger. That explains why the change in entropy is larger when the temperature is lower.
