Intensive vs extensive; classify given properties
Short answer
Intensive properties are mass‑independent (temperature, pressure, specific volume); extensive properties scale with mass (volume). Classification: volume – extensive; specific volume, temperature, pressure – intensive.
Differentiate between intensive and extensive property. State whether the following properties are intensive or extensive volume, specific volume, temperature and pressure.
| Basis | Intensive property | Extensive property |
|---|---|---|
| Dependence on mass | Independent of mass/size | Proportional to mass/size |
| On dividing the system | Stays the same | Gets divided |
| Additive | No | Yes |
| Examples | Temperature, pressure, density | Volume, mass, energy, entropy |
Classification
| Property | Type | Reason |
|---|---|---|
| Volume | Extensive | Doubles if the mass is doubled |
| Specific volume | Intensive | v = V/m, per unit mass; does not depend on size |
| Temperature | Intensive | Same in each part of a system in equilibrium |
| Pressure | Intensive | Same in each part of a system in equilibrium |
