Chapter 10, Problem 9PS

Interpretation Introduction

Interpretation:

The final pressure of gas at $\text{0°C}$ has to be given if the initial pressure was $\text{380}\text{mm}\text{Hg}$ at $\text{25°C}$

Concept Introduction:

Different laws have been put forward to introduce properties of gases:

Boyle’s law:

At fixed temperature, the volume of a fixed amount of gas is inversely proportional to the pressure exerted by the gas.

  $\text{P}\propto \frac{\text{1}}{\text{V}}\left(\text{n}\text{,}\text{v}\text{will}\text{be}\text{constant}\right)$

Charles’s law:

States that volume is directly proportional to temperature when the gas is held at constant pressure and number of molecules.

$\text{V}\propto \text{T}$

General Gas Law: Combining Charles’s law and Boyle’s law we get the General gas law or combined gas law.

  $\frac{{\text{P}}_{\text{1}}{\text{V}}_{\text{1}}}{{\text{T}}_{\text{1}}}\text{=}\frac{{\text{P}}_{\text{2}}{\text{V}}_{\text{2}}}{{\text{T}}_{\text{2}}}$
