Interpretation Introduction

Interpretation:

Whether the combination of cork and lead will sink or float is to be determined.

Concept introduction:

Volume is an important physical quantity in chemistry that is measured by the SI unit called cubic meter $\left({\text{m}}^{\text{3}}\right)$

It is defined as the quantity of space occupied by a cube with edge length of $1\text{m}$. An important unit used for expressing volume is liter $\left(\text{L}\right)$. 1 liter refers to the volume of a cube with edge length of $\text{1}\text{dm}$ that is $1\text{L}=1{\text{dm}}^{\text{3}}$.

The density of any object is obtained when the mass of object in grams is divided by volume of an object in milliliters. So it is denoted by unit: gram per milliliter.

Density is directly associated to the mass of an object. The higher the mass of the substance higher will be its density. Density is inversely associated to the volume of a substance. The lower the volume of the substance higher will be its density.

Density is associated to how the particles are packed in a substance, which in turn determines its state. The state of a substance defines the density.
