Final answer:
The length of the rope, which is 4.2 feet, is an example of an extensive property. Extensive properties depend on the amount of matter present, while intensive properties do not.
Step-by-step explanation:
The length of the rope, which is 4.2 feet, is an example of an extensive property. Extensive properties depend on the amount of matter present, so as the amount of rope increases, the length also increases. In contrast, intensive properties do not depend on the amount of matter. An example of an intensive property is temperature.
