Study Notes
Thermodynamic Properties
- Intensity and Extensity: Two types of properties in thermodynamics
- Intensive Property: A property that is independent of the size of the system
- Extensive Property: A property that is additive for subsystems
- Origin of Terms: The terms 'intensive and extensive quantities' were introduced into physics by Gabriel Fahrenheit
-
Examples:
- Intensive Property: Temperature (e.g., 20°C) is an example, as it remains the same regardless of the system's size
- Extensive Property: Mass (e.g., 10 kg) is an example, as it adds up when combining subsystems
Test your knowledge on the classification of properties in materials and systems as either intensive or extensive. Learn about the origins of these terms and their significance in physics and chemistry.
