Chapter 5, Problem 5.96PAE

Interpretation Introduction

Interpretation:

You are designing a warning system for a semiconductor fabrication facility that must have fewer than 1000 oxygen molecules per cm3 to operate successfully. While researching possible design options, you learn about a new sensor that can detect partial pressures of oxygen in the range of $1-2\text{ μbar}$. If the sensor can be used as the basis for your warning system should be explained.

Concept introduction:

An ideal gas which is known as the perfect gas is a gas whose volume V, Pressure P and temperature T are related through the ideal gas

$\text{PV = nRT}$

Here,

n = number of moles of the gas

R = ideal gas constant

T = Temperature

P = Pressure

Ideal gases are described as the molecules which have negligible size but have an average molar kinetic energy which is dependent on the temperature. When temperature is low most of the gases behave like ideal gases and the ideal gas law might be applied to them.
