The cases you'll study are: Direct Variation, where one variable is a constant multiple of another. Inverse or Indirect Variation, where when one of the variables increases, the other one decreases (their product is constant) Joint Variation, where more than two variables are related directly.

The fundamental thermodynamic variables b are the pressure (p), temperature (T), internal energy (U), and entropy (S). Added to this list are the derived variables enthalpy (H), Helmholtz free energy (A), and Gibbs free energy (G). These last three are defined in terms of the fundamental variables through the equations.

A variable may also be called a data item. Age, sex, business income and expenses, country of birth, capital expenditure, class grades, eye colour and vehicle type are examples of variables. It is called a variable because the value may vary between data units in a population, and may change in value over time.
