Which statement describes an intensive property of matter?

A. it is the same for every sample of a single substance

B. it depends on how a substance was formed

C. it is the same for every sample of every substance

D. it depends on the amount of substance present

Answer: C. it is the same for every sample of every substance

Matter is the same for every sample of every substance. The intensive physical properties of matter include pressure, density, the boiling point, the melting point, the color, etc. they are non-additive. Intensive properties are used to determine the identity of a substance. The intensive properties of matter describe only the type of matter in a sample unlike the extensive properties that describe the amount.

A substance is matter with a definite and uniform composition. Since every sample has the same composition, the intensive properties gotten from every sample of a given substance are identical. In chemistry generally, a substance is any form of matter having constant characteristic properties and chemical compositions.

How does 3D printing work?

There are three different ways 3D printers work but they all rely on the printer converting a design into individual 2D slices which are then combined to make the final 3D object. The first method uses a pool of chemicals that turns solid when light, typically a UV laser, is shone on to it. The […]
