Chapter 6, Problem 130SAE

Interpretation Introduction

(a)

Interpretation:

The symbol atm should be defined and explained.

Concept introduction:

A force which is exerted by the substance per unit area of other substance is known as pressure. It can be measured in different units like Pascal, atm, bar, torr, etc.

Interpretation Introduction

(b)

Interpretation:

The symbol STP should be defined and explained.

Concept introduction:

Under standard conditions of P, V and T, all gases behave like ideal gas. All ideal gases follow the Ideal gas equation which is combination of certain gases laws. These gas laws are Boyle’s law, Charles’s law, Avogadro law etc. The combination of all these gas laws is called as combine gas law.

Interpretation Introduction

(c)

Interpretation:

The symbol R should be defined and explained.

Interpretation Introduction

(d)

Interpretation:

The partial pressure should be defined and explained.

Concept introduction:

In a gas mixture, each gas component exerts some pressure. The sum of all gas pressure values is equal to the total pressure of the mixture. The Dalton law of partial pressure of gas can be written as

${\text{P}}_{\text{total}}{\text{= P}}_{\text{1}}{\text{+ P}}_{\text{2}}{\text{+ P}}_{\text{3}}\text{…}\text{.}$

Interpretation Introduction

(e)

Interpretation:

The symbol ${\text{u}}_{\text{rms}}$ should be defined and explained.

Concept introduction:

In a gas mixture, all gas particles remain in continuous motion. All gas particles have different speed. Particles are moving in reverse directions and have velocities of different signs.
