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.

Help Recycling

The most obvious things to reuse are plastic, glass, metal, and paper or fabric (paper and organic fabric are made of the same component, cellulose, and are recycled in a similar way). The color-coded trash bins show where each of these components can be put to be recycled in a proper way.
