1 THERMODYNAMICS Thermodynamics is the branch of science
... Since a thermodynamic property is a function of the state of a system, it is referred to as a point function or a state function. There are two kinds of thermodynamic properties namely intensive and extensive. Intensive property Intensive property is independent of the extent or mass of the system. ...
