Chapter 5, Problem 5.58QP

Interpretation Introduction

Interpretation:

New volume of the balloon has to be calculated if helium gas filled balloon at $\text{25°C}$ and $\text{1}\text{.00}\text{atm}$ with a volume of $\text{2}\text{.50}\text{L}$ is released and it rises to an altitude where pressure is $\text{0}\text{.800}\text{atm}$ at $\text{20}\text{°C}$.

Concept Introduction:

Combined gas law is the one that is derived from Boyle’s law and Charles’s law.  This can be represented in equation form as,

    $\frac{P_i{V}_i}{T_i}=\frac{P_f{V}_f}{T_f}$

Where,

    $P_i$ and $P_f$ are pressure of initial and final respectively.

    $V_i$ and $V_f$ are volume of initial and final respectively.

    $T_i$ and $T_f$ are temperature of initial and final respectively.
