A certain flexible weather balloon contains 3.5 L of helium gas. Initially, the balloon is in WP at 8500ft, where the temperatur
Advocard [28]

Answer:

\large \boxed{\text{3.9 L}}

Explanation:

We can use the Combined Gas Laws to solve this problem

\dfrac{p_{1}V_{1} }{T_{1}}  =  \dfrac{p_{2}V_{2}}{T_{2}}

Data

p₁ = 571.2 Torr;  p₂ = 400 Torr

V₁ = 3.5 L;          V₂ = ?

T₁ = 21.5 °C;        T₂ = 6.8 °C

Calculations

(a) Convert the temperatures to kelvins

T₁ = (21.55 + 273.15) K = 294.70 K

T₂ =   (6.8  + 273.15) K = 279.95  K

(b) Calculate the new volume

\begin{array}{rcl}\dfrac{p_{1}V_{1} }{T_{1}} & = & \dfrac{p_{2}V_{2}}{T_{2}}\\\\\dfrac{\text{571.2 Torr $\times$ 3.5 L}}{\text{294.65 K}} & = & \dfrac{\text{400 Torr} \times V_{2}}{\text{279.95 K}}\\\\\text{6.78 L} & = & \text{1.429V}_{2}\\\\V_{2} & = & \textbf{4.7 L}\\\end{array}\\\text{The new volume of the balloon is $\large \boxed{\textbf{4.7 L}}$}
