Two side-by-side diagrams of a spherical gas balloon. On the left, labeled Initial State, the balloon is in air with temperature T_0 and volume V_0. On the right, labeled Final State, the balloon is submerged in a container of cool water at temperature 3/4 T_0, appearing smaller. Small inward-pointing arrows on both balloons represent constant external atmospheric pressure P_0. No other labels, lines, text, or axes appear.
A flexible gas balloon placed into a cool water bath at constant pressure.
A flexible gas-filled balloon has an initial volume \(V_0\) at an absolute temperature \(T_0\). The balloon is placed into a cool water bath while the pressure of the gas remains constant. Once thermal equilibrium is reached, the absolute temperature of the gas inside the balloon is \(\dfrac{3}{4}T_0\). What is the new volume of the balloon?
