Why is Cpln(T2/T1) Zero for Isothermal Entropy Change?

Click For Summary
SUMMARY

The equation Cpln(T2/T1) = 0 holds true during isothermal processes because T2 equals T1, resulting in the natural logarithm of 1, which is zero. This conclusion is reinforced by the understanding that during isothermal expansion, the temperature remains constant, leading to no change in entropy. The discussion highlights the importance of recognizing the relationship between temperature and entropy in thermodynamic processes.

Can someone explain to me why Cpln(T2/T1) = 0?

Thank you.

Thank you.

Expanding isothermally means that T2 = T1.
 
Ok sorry... I forget about this concept. sorry thanks for your explanation Chestermiller :)
