Chapter 13, Problem 134AP

Interpretation Introduction

Interpretation:

To calculate the pressure of Argon gas at constant conditions of temperature and volume.

Concept Introduction:

The ideal gas equation is;

PV = nRT

• P = pressure.
• T = temperature.
• V = volume.
• R = gas constant = 0.0821 L. atm / K. mole.
• n = number of moles.
Hence at constant volume and temperature, the pressure is directly proportional to moles of gas. The mathematical expression can be written as;

$\frac{{\text{P}}_{\text{1}}}{{\text{n}}_{\text{1}}}\text{=}\frac{{\text{P}}_{\text{2}}^{}}{{\text{n}}_{\text{2}}}$
