Relationship between S & T

[Alexia_Vanegas_1G]

Why does an increase in temperature increase entropy if temperature is in the denominator? Is it because there is an increase of heat being added?

It's because adding more energy to the system excites the molecules and there is more disorder and chaos, which is what entropy is measuring.

To determine entropy, you would only use (deltaS)= (q(rev))/T for an isothermal process. (by context of your question I am assuming you are thinking of this equation) However, since there is a change of temperature, you would use the equation (deltaS)=n(Cp)(ln(T2/T1)). For an increase in temperature, the value of ln(T2/T1) will always be a positive number, resulting in an increase in entropy.

I hope this helps!
