What is the difference between an intensive and extensive property? What are examples of each? Intensive properties, like density, don’t depend on the amount of matter. They are useful in describing and identifying a substance. Besides density, other intensive properties are MP and BP. Extensive properties would be mass or volume because they are different for each size of sample. How do sfs dictate certainty? The more sfs there are, the more precise your value is How many sfs are th...
