Isotherms of an ideal gas for different temperatures. The curved lines are rectangular hyperbolae of the form y = a/x. They represent the relationship between pressure (on the vertical axis) and volume (on the horizontal axis) for an ideal gas at different temperatures: lines that are farther away from the origin (that is, lines that are nearer to the top right-hand corner of the diagram ...

Conversely, every rational PV number is an integer greater than 1. If α is an irrational PV number whose minimal polynomial ends in k then α is greater than |k |. If α is a PV number then so are its powers α k, for all positive integer exponents k. Every real algebraic number field K of degree n contains a PV number of degree n. This number ...

It is also possible to evaluate the enthalpy of one reaction from the enthalpies of a number of other reactions whose sum is the reaction of interest, and these not need be formation reactions. This method is based on Hess's law , which states that the enthalpy change is the same for a chemical reaction which occurs as a single reaction or in ...
In thermodynamics, the Gibbs free energy (or Gibbs energy as the recommended name; symbol ) is a thermodynamic potential that can be used to calculate the maximum amount of work, other than pressure–volume work, that may be performed by a thermodynamically closed system at constant temperature and pressure.
With Present Value under uncertainty, future dividends are replaced by their conditional expectation. Traditional Present Value Approach – in this approach a single set of estimated cash flows and a single interest rate (commensurate with the risk, typically a weighted average of cost components) will be used to estimate the fair value.
Thus, as shown above, the partition function plays the role of a normalizing constant (note that it does not depend on s), ensuring that the probabilities sum up to one: = = = This is the reason for calling Z the "partition function": it encodes how the probabilities are partitioned among the different microstates, based on their individual ...
