Thermodynamic function of an ideal gas

Thermodynamic function of an ideal gas is described by  a following function 

1. Internal energy:

Its is define as the sum of kinetic energy and potential energy. it is denoted by the symbol   U. its  measured in the unit of kilojoule per mole.

some of the properties of the  internal energy are:

2.Enthalpy.

it is  define as the  total heat content of a substance that is available for a conversion to heat at constant temperature and pressure. It is measured in unit of energy such as joule or kilojoule per mole

In mathematically enthalpy is also define as the sum of  internal energy and product of pressure volume  of a system( H=U+PV)

some of the properties of the  Enthalpy are

3. Gibb's Free Energy.

The thermodynamic function that is used to measure maximum amount  of work done in any thermodynamic when the temperature and the pressure of the system are kept constant. Gibb's free energy is denoted by symbol  G. Gibb's free energy is measure in joule or calories.  In mathematically Gibb's free energy is define as enthalpy minus product of temperature and entropy (G=H-TS).

some of the  Properties of the Gibb's free energy are:

1.Gibb's free energy is state function. Which means that the values of G  depend on the current state of system not on how the system arrived at that state.

2. It determine whether the process spontaneous or not. If the Values of G is positive Indicates that process is spontaneous. If the values of G is negative indicates that process is not spontaneous.

These are thermodynamic function of an ideal gas.
