Consider a steaming aluminum soda-pop can that contains a small amount of boiling water. When it is quickly inverted into a bath of cooler water the can is dramatically crushed by atmospheric pressure. This occurs because the pressure inside the can is rapidly reduced by A) contact with the relatively cool water. B) sudden slowing of the air and steam molecules inside. C) condensation of steam inside. D) reduced internal energy. E) rapid conduction of heat to the relatively cool water.

Henry's law states that the solubility of a gas is directly proportional to its partial pressure, LaTeX: S_g=k/cdot P_gS g = k ⋅ P g, where Sg is the solubility of the gas, Pg is the partial pressure of the gas, and k is the Henry's law constant for a specific gas at a specified temperature. What is the millimolar solubility of oxygen when the atmospheric pressure is 705 mmHg? Air is composed of 21% oxygen by moles. The Henry's law constant for oxygen is 1.3x10-3 mol/L-atm.
