Chapter 1, Problem 1.40P

Interpretation Introduction

Interpretation:

The metal in each cylinder is to be identified on the basis of their densities.

Concept introduction:

The density of the substance is defined as the mass per unit volume. It is represented by $\rho$ and its unit is ${\text{kg/m}}^3$.

The formula to calculate the density of the substance is as follows:

$\text{Density of substance}\left(\rho \right)=\frac{\text{Mass of substance}\left(M\right)}{\text{Volume of substance}\left(V\right)}$        (1)
