Chapter 11, Problem 24QP

Interpretation Introduction

Interpretation:

The reason thata stainless-steelrazor blade floats on water is to be explained.

Concept introduction:

A substance, whose density is less than water, floats in water.

The density of a substance depends on its ratio of mass and volume.

Surface tension is the force per unit length at the surface of the liquid.

Surface tension is due to presence of intermolecular forces.

The various kinds of interactions that bind a molecule are known as intermolecular forces. These can be dispersion, dipole–dipole, ion–dipole, and hydrogen bonding.

Water has high surface tension due to presence of hydrogen bonding.
