Chapter 7, Problem 7.128QP

Interpretation Introduction

Interpretation:

The uncertainty in speed of oxygen has to be calculated using position and mass of the oxygen molecule.

Concept introduction:

Heisenberg uncertainty principle:

It is not possible to identify both the particle’s momentum and position at same time with certainty.  It is given as mathematical equation

$\text{Δx}\text{Δp}\ge \frac{\text{h}}{\text{4π}}$

Where,

$\text{Δx}$ is uncertainty in position of particle

$\text{Δp}$ is uncertainty in momentum of particle.

h is Planck’s constant.
