Question

Are the following quanities extensive or intensive, a) inertia b) velocity c) the product of inertia and velocity?

Answer 1

In physics and chemistry an intensive property of a system is a physical property of the system that does not depend on the system size or the amount of material in the system.

And if their property depends on system size or amount than it is Extensive.

a)Inertia is an extensive property of a substance proportional to its mass, and therefore depends on the amount of the sample.

b)

Velocity is intensive.The value of an intensive property may vary with time and its position within the system.

c)

Since in product one is extensive which depend their size or amount so resultant must be extensive.
