Summary Introduction

To determine:

The final pressure of the gas in the cylinder for the given initial and final atmospheric conditions.

Introduction:

Charles’s law, Boyle’s law and Gay Lussac’s law are combined together to give a final gas equation known as combined gas law. The value of pressure, volume and temperature remains same for the same amount of the gas. This equation is mathematically expressed as,

$\frac{P_1{V}_1}{T_1}=\frac{P_2{V}_2}{T_2}$ (1)

Where,

• $P_1$ is the initial pressure of the gas.
• $P_2$ is the final pressure of the gas.
• $V_1$ is the initial volume of the gas.
• $V_2$ is the final volume of the gas.
• $T_1$ is the initial temperature of the gas.
• $T_2$ is the final temperature of the gas.
