14.2.2. Extensive vs Intensive Properties

Try these first

1. 1.

   What are extensive properties?

   Hint

   Think about how the properties change with more mass.

2. 2.

   Give an example of an intensive property.

   Hint

   What properties remain the same no matter how much you have?

3. 3.

   Which of the following is an extensive property?

   • Pressure
   • Temperature
   • Mass

   Hint

   Consider what happens to the property as mass changes.

4. 4.

   True or False: Intensive properties depend on the amount of mass in a system.

   • True
   • False

   Hint

   What properties stay the same no matter how much you have?

5. 5.

   In a closed system, the mass increases from 5 kg to 10 kg. Describe how the extensive properties change and provide a mathematical representation for one of them.

   Hint

   How does energy relate to mass?

6. 6.

   If you are analyzing a fluid system that has variable density, discuss how both extensive and intensive properties can be calculated in this scenario.

   Hint

   Consider how you measure density and energy at different points.
