Chapter 6, Problem 76E

Interpretation Introduction

Interpretation:

One Nobel gas should be determined whose root mean square speed is higher than the speed of the rifle bullet along with the one Nobel gas which has lower speed at 25 degree Celsius.

Concept introduction:

${\text{u}}_{\text{rms}}$ of any gas molecule can be defined as the root mean square velocity of gaseous molecules.

The mathematical representation of ${\text{u}}_{\text{rms}}$ is:

${\text{u}}_{\text{rms}}\text{= }\sqrt{\frac{\text{3RT }}{\text{M}}}$

Here:

• R = gas constant = $\text{8}\text{.3145 J/K}\cdot \text{mole}$
• T = Temperature in K
• M = Molar mass ( kg/mole)
