Answer:

1. Density of the rectangular prism is 20 g/cm3

2. A material's ability to dissolve : Soubility

3. Intensive property : A physical property that is independent of sample size.

Explanation:

Volume of Prism is calculated by :

$volume = L\times W\times H$

Length = 3 cm

Width = 2 cm

Height = 1 cm

$volume = 3\times 2\times 1$

V = 6 cm3

mass = 120 g

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

$Density = \frac{120}{6}$

Density = 20 g/cm3

Solubility :

It is the chemical property of the substance.

It shows the ability of the solute to dissolve in the solvent at a given temperature.

Intensive Properties:

These are bulk properties(Do not depend upon the amount of matter present)
They are independent of sample size.
Example : boiling point,melting point,temperature,refractive index
