The energy associated with molecular motion. The temperature The temperature T of a material is a measure of its internal energy U:
U = f(T) ; i.e U is a function temperature.
The internal energy is a state function of a system, because its value depends only on the current state of the system and not on the path taken or process undergone to arrive at this state. It is an extensive quantity. The SI unit of energy is the joule ( J ). Sometimes a corresponding intensive thermodynamic property called specific internal energy is defined, which is internal energy per a unit of mass of the system in question. As such, the SI unit of specific internal energy is joules/kilogram (J/kg). If intensive internal energy is expressed on a per mole basis, then it is referred to as molar internal energy and the unit is joule/mole (J/mol).
The path integral Monte Carlo method is a numerical approach for determining the values of the internal energy, based on quantum dynamical principles.
