Question
What are intensive and extensive variables? Give examples.
Advertisements
Solution
- Extensive variable depends on the size or mass of the system.
Example: Volume, total mass, entropy, internal energy, heat capacity, etc. - Intensive variables do not depend on the size or mass of the system.
Example: Temperature, pressure, specific heat capacity, density, etc.
