11. At the end of a cooking cycle, a pressure cooker contains a mixture of water, steam, and food at a temperature of 120°C and 1.5 atm of pressure. The pressure is valve is opened and the pressure decreases, which alters water's boiling point and causes the contents of the pressure cooker to cool rapidly. Which statement best explains why the contents cooled rapidly after the pressure was released? A. Water lost heat as it vaporized. B. Water absorbed heat as it vaporized. C. Water lost heat as it condensed. D. Water absorbed heat as it condensed.
