An air bubble of volume \( 15 \mathrm{~cm}^{3} \) is at the bottom of a lake \( 40 \mathrm{~m} \) deep, where the temperature is \( 4.0^{\circ} \mathrm{C} \). The bubble rises to the surface, which is at a temperature of \( 20^{\circ} \mathrm{C} \). Take the temperature of the bubble's air to be the same as that of the surrounding water. Just as the bubble reaches the surface, what is its volume?
