Physical Chemistry Chapter 2 Thermodynamic Properties of system Extensive property: The value of the property changes according to the amount of material which is l present( e. g, mass, volume, internal energy) e Intensive property: independent of the amount of material which is present(e.g temperature, density) State functions: the value of a particular property for a system depends solely on the state of the system at time(e.g, pressure, volume, internal energy, entropy Path functions: A property depends upon the path by e which a system in one state is changed into another state(e.g, work, heat7 Extensive property ： The value of the property changes according to the amount of material which is present (e.g., mass, volume, internal energy) Intensive property：independent of the amount of material which is present (e.g., temperature, density) Thermodynamic Properties of system State functions: the value of a particular property for a system depends solely on the state of the system at time (e.g., pressure, volume, internal energy, entropy) Path functions: A property depends upon the path by which a system in one state is changed into another state (e.g., work, heat) Physical Chemistry Chapter 2
