Question

Physical properties can be used to describe matter. Some properties are dependent on the amount of matter present. All BUT ONE of these physical properties changes with the amount of matter. That is A) density. B) mass. C) volume. D) weight.

Answer 1

A. the density stays the same unless given an external catalyst

Answer 2

Answer:  A) density.

Explanation:

a) Density is defined as the mass contained per unit volume.

$Density=\frac{mass}{Volume}$

Density is an intensive property as it does not depend on the amount of substance.

b) Volume of the gas is defined as the space occupied by a substance.

c) Mass is the amount of matter contained in a substance.

d) Weight of an object is the force acting on an object by virtue of its mass. weight=$mass\times acceleration$

Volume, mass and weight are extensive properties as they all depend on the amount of substance present.
