Chapter 10, Problem 123AP

Interpretation Introduction

Interpretation:

Temperature at which the rootmean square speed of He equals to root mean square speed of Ne is to be calculated.

Concept Introduction:

The root mean square speed of a molecule can be calculated as

$u_{\text{rms}}=\sqrt{\frac{3RT}{M}}.$

Here, $u_{\text{rms}}$ represents the root mean square value of the molecule, $R$ represents gas constant, $T$ represents temperature, and $M$ represents the molar mass.

The conversion of temperature from Celsius to Kelvin is done using the formula given below:

$T\left(\text{K}\right)=T\left(°\text{C}\right)+\mathrm{273.15.}$
