Question

The volume of a balloon varies inversely withthe pressure put on it. If a weather balloon hasa volume of 500cc at 1.5 atmospheres ofpressure, what would its volume be at 4atmospheres?

Answer 1

$\begin{gathered} V=\frac{1}{P} \\ So, \\ \frac{V_2}{V_1}=\frac{P_2}{P_1} \\ \frac{V_2}{500}=\frac{4}{1.5} \\ V_2=1333.34\text{ c.c} \end{gathered}$
