Partition Function of 2 State System

Click For Summary
SUMMARY

The partition function for a two-state system with energy levels of 0 and V is correctly defined as Z = 1 + e^(-V/kT). The average energy of the system is not simply V; it is calculated using the partition function, leading to a non-zero entropy value. Specifically, the entropy of a two-state system with one state at zero energy is not zero, as entropy accounts for the distribution of states and their probabilities, which are influenced by temperature.

If I have a 2 state system with energy levels of the 2 states to be 0 and V. I find the partition function to be Z = 1 + e^(-V/kT). Am I correct? If so, does that not mean the average energy is V? and thus the entropy is 0? This doesn't make sense, how is the entropy of a 2 state system (when 1 state is zero energy) 0?!

Thanks!
