Chapter 11, Problem 11.119QP

Interpretation Introduction

Interpretation:

The purpose of hole in body of the ballpoint pen has to be explained.

Concept Introduction:

• Ballpoint pens have a hole in the surface of the body for two reasons; firstly to equalize the pressure during writing.
• The pressure exerted by an individual gas in a mixture is known as its partial pressure.
• Assuming we have a mixture of ideal gases, we can use the ideal gas law to solve problems involving gases in a mixture.
• Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases:
• ${\text{P}}_{\text{Total}}\text{}{\text{=P}}_{\text{gas 1}}\text{}{\text{+P}}_{\text{gas 2}}\text{}{\text{+P}}_{\text{gas 3}}\text{}\mathrm{....}$
