Intensive, Extensive Properties All the quantities we just discussed ( i.e. , temperature, volume, mass,  etc. ,) describe the  properties of a substance. Many properties can be classified as  extensive  or  intensive . Extensive Properties: dependent on the amount of substance. Examples: mass, volume, energy Intensive Properties: independent of the amount of substance. Examples: temperature, pressure,  density For example, if I took 1.0 liter of water at room temperature (25 °C) and added another  1.0 liter of water at the same temperature then I would have 2.0 liters of water at 25 °C.

Unformatted text preview: From this example we see that Volume and Mass are extensive properties ( i.e. , volume and mass doubled), while Temperature is an intensive property ( i.e. , temperature stayed the same). You would also expect the density to remain the same, so it is also an intensive property. In the language of thermodynamics we say: when two identical systems are brought together extensive properties will double in value, and intensive properties will stay the same . Can you explain why pressure is an intensive property?...
