Chapter 11, Problem 11.9QP

Interpretation Introduction

Interpretation:

The pressure in a cylinder containing Nitrogen continuously decreases as gas is released from it.  But the pressure in a cylinder containing Propane maintains constant pressure as propane is released.  Thus difference in behaviour is to be explained.

Concept introduction:

Gas law: Gas law states that the relationship between pressure, volume and temperature. This law is combination of Boyle’s law and Charles’s law.

• Boyle’s law (pressure-volume law): This law states that the volume of given quantity of gas detained at constant temperature diverges inversely with functional pressure when the temperature and mass are constant.

  $\text{Vα }\frac{\text{1}}{\text{P}}$

• Charles’s law (temperature-volume law): This law states that volume of given quantity of gas detained at constant pressure is directly proportional to the temperature.
