Question

What are partition functions?​

Answer 1

Answer:

Partition functions are functions of the thermodynamic state variables, such as the temperature and volume. Most of the aggregate thermodynamic variables of the system, such as the total energy, free energy, entropy, and pressure, can be expressed in terms of the partition function or its derivatives.

Explanation:

A partition of a positive integer n is an expression of n as the sum of one or more positive integers (or parts). ... The number of different partitions of n is denoted p ( n ) p(n) p(n). This function is called the partition function.
