Chapter 12, Problem 12.3QP

Interpretation Introduction

Interpretation:

The reason for stainless steel razor blade floating on water despite it has higher density than water has to be explained.

Concept Introduction:

Density of a substance is the mass of a substance occupied per unit volume.  Thus it can be represented as $\text{density}\text{=}\text{mass/volume}$.

Density of water is ${\text{1g/cm}}^3$ whereas that of stainless steel is $\text{7}\text{.7}{\text{g/cm}}^{\text{3}}$.
