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.
Give an example of an extensive property.
density
volume
mass
temperature
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
temperature
pressure
Which of the following is an extensive property?
d) Specific heat
c) Temperature
a) Density
b) Mass
Which of the following is an intensive property?
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.
