2.2. Extensive and Intensive Properties

Try these first

1. 1.

   Define extensive property and provide two examples.

   Hint

   Think of properties that change if you change the size of the object.

2. 2.

   What is an intensive property?

   Hint

   Consider properties that stay the same no matter how much substance you have.

3. 3.

   Which of the following is an extensive property?

   • Pressure
   • Density
   • Mass

   Hint

   Think about properties that change with the quantity of material.

4. 4.

   True or False: Intensive properties depend on the amount of substance present.

   • True
   • False

   Hint

   Remember, they remain the same regardless of the size of the system.

5. 5.

   If a fluid has a density of 8 kg/m³ and the volume of the fluid is 10 m³, calculate its mass. Also explain how this relates to the extensive property.

   Hint

   Use the formula of mass to find your answer.

6. 6.

   Develop a scenario in which changing an intensive property of a fluid affects its flow characteristics in an engineering system. Describe how you would evaluate the changes.

   Hint

   Think about how temperature affects the fluid's behavior in a system.
