Summary Introduction

To determine:

Volume of helium at a point when the pressure is equal to $\text{380mm Hg}$.

Introduction:

Boyle’ law explains that at a constant temperature, the volume of a gas is inversely proportional to its pressure. Standard conditions of atmospheric pressure for a gas like Helium is equal to 1 $\text{atm}$ or $\text{760mm}$ $\text{Hg}$. A child’s balloon with volume equal to $\text{8}\text{.5L}$( ${\text{V}}_1$) of helium gas, atmospheric pressure is equal to $\text{380mm Hg}$( ${\text{P}}_{\text{2}}$).
