Intensive vs Extensive

[Sydney Pell 2E]

What does it mean when properties are intensive vs extensive? For example, what makes entropy extensive?

[Manav Govil 1B]

Extensive properties depend on the sample size, such as mass and volume. Intensive properties, on the other hand, do not depend on the quantity of the sample we are looking at, such as the melting point of a sample. Samples with extensive properties can be calculated by subtracting the final amount of the sample by the initial amount. Entropy is, therefore, an example of a sample with extensive properties.

[Elizabeth Bowen 1J]

Intensive properties are more informative, since they are always the same for a certain substance (density), whereas extensive properties can be different for the same substance (you can have different volumes or masses of one substance)

[Matthew Chan 1B]

I believe that extensive properties depend on how much of a sample you have, while intensive properties don't really depend on quantity of the sample or the size of the sample, etc.

[Alexandra Bartolome 2H]

Intensive properties are properties independent of the quantity of the substance. One example is specific heat capacity since it is specified/normalized to 1 gram of a substance. Extensive properties do depend on the amount of a substance, like heat capacity.

[Nikki Razal 1L]

for an intensive property, the value of something will be the same no matter how much of a substance you have (ie, specific heat). for an extensive property, the value of something depends on how much substance you have (ie heat capacity)

[Maika Ngoie 1B]

An intensive property is a property in which the amount of material in a system does not affect its value or quantity. For an extensive property, however, the amount of material in a system does affect its value

Entropy is an extensive property because it depends on the quantity of each. For example, if you have a 6 atom molecule and a 3 atom molecule, the 6 atom molecule has a higher entropy since it can occupy more states than the latter. So in this case, since the entropy of the two molecules was dependent on the amount of atoms there were in each molecule, entropy is an extensive property.
