Answer:

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

2. A material's ability to dissolve : <u>Soubility</u>

3. <u>Intensive property</u> : 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

2.

<u>Solubility :</u>

  • It is the chemical property of the substance.
  • It shows the ability of the solute to dissolve in the solvent at a given temperature.

3.

<u>Intensive Properties:</u>

  • 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
