4B: Extensive and Intensive Properties

What is the definition of extensive properties?

• Physical properties of a system that do not depend on the amount of matter present.

• Chemical properties of a system that depend on the amount of matter present.

• Physical properties of a system that depend on the temperature of the system.

• Physical properties of a system that depend on the amount of matter present.

What is the definition of intensive properties?

• Intensive properties are chemical properties of a substance that do not depend on the amount of the substance present.

• Intensive properties are physical properties of a substance that do not depend on the amount of the substance present.

• Intensive properties are physical properties of a substance that depend on the amount of the substance present.

• Intensive properties are physical properties of a substance that vary with temperature and pressure.

Provide an example of an intensive property.

• mass

• volume

• b) Length

• c) Pressure

• a) Volume

• d) Energy

True or False: The amount of matter affects extensive properties.

• True

• Not always

• Only in certain cases

• False

True or False: Intensive properties are independent of the amount of matter.

• Partially true

• Depends on the temperature

• True

• False

How are extensive properties different from intensive properties?

• Extensive properties depend on the amount of substance present, while intensive properties do not.

• Extensive properties can be measured directly, while intensive properties require calculations.

• Extensive properties are physical properties, while intensive properties are chemical properties.

• Extensive properties are only applicable to solids, while intensive properties apply to all states of matter.

Explain how the concept of extensive and intensive properties is applied in the field of thermodynamics.

• Extensive properties depend on the temperature of the system, while intensive properties do not.

• Extensive properties are only applicable to gases, while intensive properties apply to all states of matter.

• Extensive properties are independent of the system's composition, while intensive properties are not.

• Extensive properties depend on the size or amount of the system, while intensive properties do not.
