Chapter 8, Problem 8.64AP

Interpretation Introduction

Interpretation:

The volume of the hydrogen at $\text{0°C}\text{and}\text{1}\text{atm}\text{pressure}$ should be identified if it has an initial volume of $\text{75}\text{.4}\text{mL}\text{at}\text{748}\text{mm}\text{Hg}\text{and}\text{23°C}$

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.

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

Charles’s law: States that volume is directly proportional to temperature when the gas is held

at constant pressure and number of molecules.

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

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