Chapter 1, Problem 1A.9E

Interpretation Introduction

Interpretation:

The temperature at which helium gas cooled to reduce its volume has to be calculated.

Concept Introduction:

Combined gas equation:

At constant number of mole, the product of initial pressure, volume and temperature are equal to the final pressure, volume and temperature.

    $\begin{array}{l}\frac{{\text{P}}_{\text{1}}{\text{V}}_{\text{1}}}{{\text{T}}_{\text{1}}}\text{=}\frac{{\text{P}}_{\text{2}}{\text{V}}_{\text{2}}}{{\text{T}}_{\text{2}}}\\ \text{Where,}\\ {\text{P}}_{\text{1}}\text{-Initial presure}\\ {\text{T}}_{\text{1}}\text{-}\text{Initial}\text{temperature}\\ {\text{V}}_{\text{1}}\text{-}\text{Initial}\text{volume}\\ {\text{P}}_{\text{2}}\text{-Final}\text{presure}\\ {\text{T}}_{\text{2}}\text{-}\text{Final}\text{temperature}\\ {\text{V}}_{\text{2}}\text{-}\text{Final}\text{volume}\end{array}$
