what does it mean when it says that entropy is an intensive property?

Entropy is actually an extensive property, where the value depends on size or mass. Intensive means the value does not depend on the size.

Intensive properties do not depend on the amount of substance and is usually constant units. Like specific heat capacity is an intensive property

entropy is actually an extensive property ( it depends on the mass)

Entropy is an extensive property, meaning its value changes with the amount of the substance. An intensive property does not depend on the amount.

For these questions, I find it really helpful to imagine a glass half-full of water. For this glass, as for any system, you would be able to assign specific values to different properties. If, by filling the glass up all the way, one of these values would change, then that corresponding property is extensive. For example, if I fill up the glass, the temperature of the water would not change, so temperature is an intensive property. But in the same scenario, an extensive property like mass or internal energy would change.

Can certain extensive properties be manipulated to produce corresponding intensive values? I'm thinking of heat energy versus temperature here, but I'm not sure how the quantities compare.

Intensive properties do not depend on the amount of substances in the system, whereas extensive properties would be affected by the mass. Entropy is actually an extensive property.

Entropy is not an intensive property; it is an extensive property and state function that depends on the mass and the current state of the substance.
