Extensive Properties
- Properties which are dependent on the amount of the substance.
- e.g. volume, mass, total energy.
- Extensive properties per unit mass are called specific properties.
- Specific volume
- Extensive properties per unit mass are called specific properties.
- where
- v = specific volume [m3 kg-1]
- V = volume [m3]
- m = mass [kg]
- V = volume [m3]
- Specific energy
- where
- e = specific energy [kJ kg-1]
- E = energy [kJ]
- m = mass [kg]
- E = energy [kJ]
- Specific internal energy
- where
- u = specific internal energy [kJ kg-1]
- U = internal energy [kJ]
- m = mass [kg]
- U = internal energy [kJ]
