Question: A glass bottle is almost filled with 0.75 L of wine. It is tightly sealed, leaving a bubble of air within at atmospheric pressure and with a volume of 0.09 L. The bottle is placed in a freezer and brought to a temperature of 250 K. The wine freezes, and in so doing, expands to occupy a volume of 0.79 L.
Assume that the volume of the bottle is unchanged. What is the pressure of the bubble now that it is squeezed into a volume of 0.05 L? What is the approximate force on the cork?
